25 Incredibly Useful and Cool Firefox Addons for Geeks and Web Developers

Hey guys, a lot of people (well, not so much 🙂 ) have asked me what Firefox addons am I using. Here I’m compiling a list of my 25 favorite Firefox addons. I cannot even think of surviving a day without most of them.

1. AdBlock Plus adblock-plus-icon

This is the first addon I always install when I freshly installs Firefox. AdBlock blocks annoying advertisements from websites and emails. Some people says blocking advertisements in websites is un-ethical and thereby we are attacking the ability of website owners to earn revenue from their efforts. Well, it is another whole talk, so it’s up to you. (Anyway I love it)

2. Web Developer ToolbarWeb-Developer-icon

An incredible MUST HAVE for all web developers. This addon is like a Swiss knife and has a lot of functions. Believe me, if you have never used it before, you will thank me once you install it and feel it. It enables you to manage cookies, images, java, javascript.. No no, I cannot even list them. Try yourself.

3. Firebugfirebug-icon

Another incredible one. This one is a little difficult to get used to. But once you get used to it, you will bow to it. Incredible tool for debugging your layout, analyzing and optimizing your sites performance etc etc.

4. Zoterozotero-icon

Like firebug, you may not like this addon on first bite, but if you are inclined to learning new stuff and taking notes, you will never again part with this addon. Very easy to save web pages, links and stuff. Every student who uses the internet for academic purposes in any way MUST have this. Once I downgraded my Firefox to an older version, just because Zotero was not working in the newer version of Firefox. (Now it is updated and works with the latest releases till date)

5. TryAgain addon

(Not compatible with Firefox 3.6)

This is a simple but very useful addon. If a page fails to load, this addon will keep trying until the page is loaded. Very very useful if you have a slow or not-so-good internet connection. This one was my fav with AdBlock, but this addon is not compatible with Firefox 3.6. I’m just hoping the author will update the addon soon.

6. Firesomethingaddon

Firesomething is not very useful, like the addons we discussed above. But I keep it for mere geek pleasure. This addon will let you change the name of your Mozilla Firefox to something else you like. It also has a set of preset random names. Right now, as of we speaking, the title of my Firefox reads – Mozilla SulpherMonkey. Isn’t that hilarious? (watever, I love it). You can also change the Firefox logo in the About box.

7. YSlowyslow-icon

Another pretty useful addon for web developers. Useful for analyzing your website’s performance based on several criteria. The best part is, it is developed by Yahoo!

8. User Agent SwitcherUser-Agent-Switcher-icon

A cool geeky addon. This addon can be used to fake your browser’s user agent. S’pose if a website is allowing access to only Internet Explorer users, then this addon can help you. I have narrated another cool use of this addon in my previous post.

9. FEBEFEBE-icon

FEBE Stands for Firefox Environment Backup Extension. With this addon, you can all your addons, preferences, saved passwords and a lot more. Also you can restore your backups at a later time. I recommend this addon very much. I owe so much to this addon for saving me a lot of time, work and data. (You can also export all your installed addons as a single installable addon)

10. Fissionfission-icon


Fission is another geeky addon. Using this addon, you can combine your address bar and loading/progress bar, as in windows 7 and vista. Very geeky.

11. ColorfulTabscolorfultabs-icon


Another super-geeky addon. This addon will give different colors to different tabs. Will look really attractive if you work with a lot of tabs open. (After installing this addon, I even thought the default tab color is boring)

12. MeasureITaddon


A useful and handy tool for web and layout designers. This addon will enable you to measure the the dimensions of objects in a webpage.

13. CookieSwapcookieswap-icon

This tab will enable you to have and easily manage multiple profile in Firefox. Has other uses too. Suppose you have 50 tabs open in your browser and you have logged in you your GMail account. payPal account, blog and a few other sites. Suppose if you want to go out for a quick bite or something. It won’t be wise to leave the browser open and leave the computer if you are logged into many important site. And if you close all the tabs of just log out of those sites, it will be a chore to log back into each one of them when you come back. In that case use this addon and just switch to a different profile when you go out and you will be automatically logged out of all the sites. When you come back, just switch back to the previous profile, and you are logged in.

14. FoxTabfoxtab-icon

FoxTab is a cool addon that will let you flip through your Firefox tabs in 3D. The addon is highly customizable and stylish, and sure geeky.

15. View Source Chartview-source-chart-icon

This addon lets us view the source of web pages in an easy to understand manner. Different regions – head, body, divs etc are given in different, easily distinguishable colors. Handy. (No, it doesn’t highlight syntax)

16. xclearaddon


xclear comes in handly when you want to quickly clear your address bar or search box. Give it a try, you will like it.

17. ColorZillacolorzilla-icon

ColorZilla is very useful for web designers. It comes with a color picker (eye dropper), with which you can find the hexadecimal color code of any element in a page.

18. Total validatortotal-validator-icon

Total validator is a one-stop all-in-one validator comprising a HTML validator, an accessibility validator, a spelling validator, a broken links validator, and the ability to take screenshots with different browsers to see what your web pages really look like. It is very easy to use too. The only problem is that it needs an internet connection to function.

19. TabRenamizerTabRenamizer-icon

This is an incredibly useful addon. It can be used to change the title and favicon of tabs opened in your Firefox window. You can rename all tabs with a shortcut. Comes in totally handy if you want to quickly hide what sites you have opened.

20. Locationbar 2locationbar-icon

Locationbar 2 will can segment the url in your address bar for easier navigation to other parts of the same site. I have described a use of this addon in another post – 7 Points to Stay safe in the Social Web.

21. Leet Keyaddon


A cool geeky addon with which you can easily type in 1337, ROT13, Hexadecimal, Morse, Binary etc (and more) and type and encrypt text using DES and AES. This one is incredibly geeky and can be used to surprise your friends by quickly type in reverse or in 1337 (h4x0r) when you are chatting.

22. ReminderFoxReminderFox-icon

Easily manage your schedule and set remainders and alarms in your browser. This one is also a featured Firefox addon.

23. ScreenGrabScreenGrab-icon

ScreenGrab enables you to quickly takes screenshots of web pages. The best feature is that we can even decide whether to take the screenshot of only the visible portion or whether the whole page.

24. <

Now tell me what you think and what your favorite addons are. Also, give some love by using the social bookmark icons below.

Browse in iPhone without an iPhone (Android too)

Hey guys, ever wanted to see how Gmail looks in iPhone? Well, look below.

I don’t own an iPhone, and definitely the window size in the above screenshot is wider than an iPhone. Here is what I did.

Step 1: Installed the Firefox addon called User Agent Switcher.

Step 2: Switched my user agent to the ‘iPhone user agent’

Step 3: Opened GMail as normal.

(Sorry if you were expecting more. but that’s all)

Is there anything useful in this?

Yes. Besides just curiosity, this technique of switching user-agents are sometimes useful too.

How is it useful?

A lot of websites are optimized for mobile use. So if you visit them using a mobile user-agent, you will be presented with a low-weight version of the site. This is very useful when you are using a slow connection (not to mention if your computer is connected to the net using your phone’s GPRS)

How much will I save?

Hmm, that depends. Just before writing this post, I accessed Gmail normally (without changing the user-agent). I measured the page load size – it was more than 2 Mb (WTF)

But when I accessed it with iPhone and Android user-agents, the page loaded in around 150 Kb.

Here see some more of the screenshots I captured with iPhone user-agent.

7 Points to Stay Safe in the Social Web

Facebook Population

How many of those people you know doesn’t have a Facebook account, or an Orkut or MySpace account? I won’t be surprised if you say your 90yr old grandmother is tweeting or your 3yr old brother is playing mafia wars in Facebook 🙂 With the ever increasing participation of people in social networking sites, the more vulnerable their security is being. As this Mashable post says, a guy named Israel Hyman posted this status message in his twitter account saying he’s enjoying his excursion to Kansas city. Later, he returned home to see that his house had been burglarized.

Ok, now let me tell you how to stay (relatively) safe on the social web.

1. Use Strong Passwords

This is the most basic rule. A complex password may be difficult to remember, but it is worth it, believe me. If you know your dad’s high school sweetheart’s name, try it as password in his mail account or Facebook account. You have good chances. Personally my mother still uses my dad’s nickname as her Gmail password. Using simple, easily guessable passwords is most common in less tech savvy people, like your parents, uncles or high school principal. Recently, a social media website called TeensInTech was hacked and a lot of confidential information were compromised. Later after investigating the issue, the company said that their easily guessable password is what gave them in.

2. Avoid easily guessable Security Questions.

Almost all websites including social networking sites rely on security questions for the purpose of retrieving account access incase if password is forgotten. Using easy to guess security questions is a more common scenario than that of using simple passwords. There was this guy in my college I had a grudge against. I found out his email id from his Orkut profile page. It was a Gmail account. I tried the ‘forgot password’ option in Gmail. I was presented with the security question he had set – “What is my college?” 😀 You guess what happened next. There was another guy whose security question was “What is my country?”. I searched for his name in Google and found that most of the results were related to brazil. So I could easily guess that he was Brazilian. Even if that is not the case, any stupid can see that there are less than 300 countries in the world and it is only a matter of time before guessing the correct one.

Avoid questions like these:

  • My mother’s maiden name? – your relatives may know that.
  • What is my pet? – Your neighbors may know that.
  • My first teacher? – Some of your friends may know that.
  • Where did I first meet my boyfriend/spouse? – At least your boyfriend knows that 😀

There are loads more.  Besides these guessable questions, avoid questions which can have only a limited set of answers, like these:

  • Which month am I born in? – It is only a matter of trying the 12 possibilities.
  • My favorite flavor of ice cream?- It is more than easy to guess, unless you are some weird Eskimo chef 🙂

3. Share less / Share wisely

The main agenda of social networking sites is to make you feel like sharing the most. These sites will make you think that it is a good thing to share everything. You will be even given option to marks some of these information as ‘private’, so that only those in your friends list will be able to see it. Believe me, you can trust no one. You won’t believe if I tell you the number of guys who have asked me to crack their girlfriends’ mail id. I regret to say that I once cracked one of my best friend’s email account, just for fun. I felt terrible after doing so, so I confessed – after a few months!

Your personal information like zip code/postal code, mobile number, birthday etc can be used to retrieve your accounts if forget your password. So it is very important to to share wisely.

Try not to share the following information in social networking sites:

  • zip code
  • address/exact location
  • email address
  • mobile number
  • birthday
  • And other similar information.

4. Add people only  you thoroughly know as your friends

Increasing our friends is one of the thing social networking sites have been doing all these days. Even 5th grade kids seem to have 999 friends. To increase our connections, these sites present several options – importing email contacts, friend suggestions etc. It is not rare getting friend requests from people we hardly know. Most of the time, we accept all the requests, just because we don’t want to say no, and appear to an anti-social jerk. Sometimes you get friend requests from total strangers, and you will accept them just because he is from your state or district. Don’t Do That.

There is this new kind of attack method crackers/hackers are using, called Social Engineering, where hackers gather your personal information and use it to access your online accounts, reset passwords etc. So as I said, when you get a friend request, examine his profile thoroughly and accept the request only if you are fully satisfied. Never accept the request if you have at least a lil bit doubt left.

No, it’s not done with yet.

Even if the friend request is from a close friend or a person you know very well, there is a good chance that you are being manipulated. It is easy for a hacker to create a copy of one of your friend’s profile and send the request. So when you get a friend’s request, first check whether he’s already in your friends list. If you already have the same friend in your list, bet one of them is fraud. If possible, call the friend and ask him whether he just send you a friend request.

5. Do not Over-Tweet.

Twitter is the most trendy social web service now. Every cat, cow and corporation now has twitter account. When it comes to posting status updates in twitter, people seem to think that it is okay to post anything. And they post information which would’ve been kept confidential otherwise.

Know your audience (followers)

If you plan to tweet about utterly personal things, it is better to keep your tweets private. If you set your tweets to be private, your status updates won’t appear in the public timeline as you post them and will not be searchable. If your friend or brother wants to follow you, you will be asked to approve first and then only they will start getting your tweets.

Even if you are just comfortable with keeping your tweets public and wants to keep them so, then it is okay, but keep an eye on what you are posting.

6. Use the address bar to visit the site.

Trust the address bar.

Do not trust links.You may receive emails, saying ‘you have one friend request, click this link to accept’ or anything like that which can be extremely convincing. Do not click on links you receive in email to log into your social networking sites. These links may lead to bogus log in pages that may exactly look like the original login page. And once you enter your username and password into it, hoping to log into the original site, rest in peace.

t if you want to log into your Facebook account or Twitter account, use your browser’s address bar to type in the address of the site. Also before entering your login details in the site, make sure the address in the url is Facebook itself. Phishers (hackers) can employ addresses similar to the original site. So it is good to double check the address. For instance, I can create a fake Facebook login page in the address www.facebook.com.login.devildesigns.net. The address looks like a genuine one (www.facebook.com) in first look. But it is actually a sub-domain, which anyone can easily create. Only careful look can make out the difference. Tip: There is this Firefox addon which highlights the original root domain. See the screenshot below.


You can see the root domain (mozilla.com) is highlighted.

7. ..And finally, Trust No One.

Just keep in mind that everyone you meet online has a good chance of being a malicious user. Trust no one (even if he’s claiming to be ur dad. no no, uncle. okay?). The world wide web is a magical world where anyone can be everyone and everywhere. One can easily disguise as someone else. When next time you get a tempting friend request from a hot young lady, just keep in mind that probably it is some fat, balding guy with his …h…d…hangin s… e … w c (guess it is enough 😉 )

Let me know your opinions/ideas through the comments.

Google is serious – HTTPS by default for GMail

Once again Google has proved that they are the number one webmail. Almost all the webmail services – GMail, YahooMail,Windows Live Mail…. – are using HTTPS for logging the users in. i.e., if you are using firefox, you will see a bluish glow in the left end of the address bar when you are accessing the sign in page of gmail (and other webmails too). And if you take a closer look, you will see the addtess of the page starts with HTTPS, rather than just HTTP.

Having HTTPS in the sign in page makes it very difficult for hackers to steal your password. But once you are loggged in successfully, the HTTPS access is switched to normal HTTP . And everything you do now with your email account -sending mails, reading mails, viewsing contact book.. – is over the normal HTTP connection. So a hacker or even a high schooler with no programming knowledge can easily see everything you are doing. So, your sensitive information is compromised.

And the solution?

In Gmail’s settings, there was this option to set full time HTTPS access to your mail account. But it was optional. Now Google has made the HTTPS mode enable by default for all mail accounts. (Still you can disable it under the settings if it is itching).

I strongly recommend everyone using the ‘always use HTTPS’ setting.

I will be writing some posts covering HTTPS and internet security soon. Come back soon. Bye now.

Bing says no PORN to Indians (How to search porn in Bing)

Two days ago, Microsoft unraveled their new search engine, Bing. I tried it. It is super cool. If you hover mouse beside a result, a short summary of the target page is displayed in a sweet non obtrusive manner (ajax). The search homepage has a new background image every day. So it always looks new and fresh.

Besides web search, Bing also offers image search, map search etc.

I was checking the image search. (It is cool). I just wanted to see if Bing has got any nude pics of Jennifer Lopez, which was scarse (and I doubt their genuineness) in Google Image search.

Jennifer Lopez nude Bing

No porn for Indians, come back after puberty!!

krack. I was stunned by the reply from Bing.

It asked me to change the keyword to get results. What the heck else should I use as keyword other than JenniferLopez nude, if I wanna see Jennifer Lopez nude??

I looked everywhere in the preferences to trun off content filter. Oops.. Then I visited Bing’s US variant. (You can access the US page either using the country changer link in the top of the page or using this URL www.bing.com/?cc=us, or use any country code there, in, uk, de etc).

So the point is Microsoft doesn’t want Indians to see porn. Hail Saint Bill Gates, our saviour.

The most funny police warrant!! For sending email and using Linux

I usually do not post about news events. But this one here made it irresistible for me to keep from blogging on it.

I got this news from the EFF Blog. A Boston University student’s computer, cell phone and other properties were seized by the police as a part of an investigation to find who send an email to the college mailing list saying that another student is a gay.


Though there is no indication of any crime he has committed, the police has issued a very stupid and funny warrant. Some of the supposedly suspicious activities listed include: the student being seen with “unknown laptop computers,” which he says he was given by Boston College for field testing or he was “fixing” them for other students; the student uses multiple names to log on to his computer; and the student uses two different operating systems, including one that is not the “regular BC operating system”(I think BC stands for Boston College. And BC operating system is some customized version of Windows) but instead has “a blackscreen with white font (I cannot stop laughing… they should have sepcified the font  size too..) which he uses prompt commands on.”

During their search, the police seized (among other things) the student’s computers, storage drives, cell phone, iPod Touch, flash drives, digital camera, and Ubuntu Linux CD ( Oh, I never knew u can send email from iPod Touch or Ubundu CD). None of these items have been returned to him.

To strengthen their arguments, the police also says the (computer science major) student is considered a computer genius by other students (Oh my god, they are hunting down geniuses,.. I must be careful 😀 😀 😀 ).

The student who was employed by college IT department was suspended from job. EFF has filed an emergency motion to quash and for the return of seized property on behalf of a Boston College computer science student Riccardo Calixte.

Round corners with CSS3. Super Cool.

I was not very fond of CSS, until recently.  I just used html elements to style my pages. But then once I happened to use some simple CSS elements, coz I had basic CSS in my college syllabus. Ever since I’m a great fan and admirer of this simple, kewl technique.. CSS.

CSS Round Corner Menu

I have been fascinated by round cornered elements in web pages. I tried to learn the ‘secret art of round corners!!’. Most of my searches returned tutorials for rounding corners using images, Including this one. It uses 4 corner images and is pretty simple to implement.

A few days ago, I was browsing through some script from DynamicDrive CSS Library, I found an unfamiliar css element: -moz-border-radius. I did a lil research and eventually I got to CSS3. Checkout www.css3.info. CSS3 is still in draft and all browsers have not started to support it. Yet some like Firefox, Safari etc has already started to adopt CSS3.

border-radius (reference) is an element which is included in the forthcoming CSS3. It can be used in the following forms.

If you use border-radius: 4em; , then all the four corners will be rounded by 4em. Or you can use border-radius: 5px 5px 0px 10px;, so you can use individual radii for all the four corners. Or the single attribute can be broken down as follows.

border-top-left-radius: 4em;
border-top-right-radius: 4em;
border-bottom-right-radius: 4em;
border-bottom-left-radius: 4em;

The Gecko Layout Engine which is the basis of Mozilla Firefox uses some equivalent attributes instead of border-radius. The border-radius equivalent in Gecko is -moz-border-radius (reference). It can also take 4 arguments as in -moz-border-radius:15px 0px 15px 0px;. If only 1 attribute is specified as in -moz-border-radius:15px;, the same will be applied for all 4 corners. -moz-border-radius can also be written as 4 different elements as follows.


Here is a few examples I made which uses the -moz-border-radius element for rounding corners. See the code of the page and see how simple it is. But remember -moz-border-radius works only in Gecko based browsers, which includes Firefox, NetScape, Camino, SeaMonkey K-Meleon etc (Google’s picture-organization software Picasa is based on Gecko).

That was Kewl, ain’t it? cya, babye.

How to find what language it is written in..

Update: This post is a bit old. For one thing, Google Translate now automatically detects language. Also better technologies for the same might have come up since I published this first.

I recently got a scrap in my orkut profile. It looked like total rubbish coz the language it was written in was totally unknown to me.

Google’s Translation service is very good and I thought of decrypting the scrap through Google Translate. Once I reached Google Translate,  I pasted the entire scrap in the box provided there… Then there was another problem.. I couldn’t specify the source language (ie, from which language to english) Aah.. then I got an idea(!!). I just pasted the whole scrap message in Google Search and searched it. Then I examined the URL’s in the search results. Amazingle, most of the search results came from sites with cc TLD (Country Code Top Leve Domain, like .in, .us etc) .br. That means thar most of the search reults are from Brazilian sites..

Yay!! So the language I got the scrap was the ‘Brazilian language’
. So which is the language of brasil, the easiest way to find such facts is google, as always. I just searched ‘language of brazil is‘ in google and it was written in the topm of the results page that ‘Portuguese’.

Now this were easy. I went to google translate and gave the source language as portuguese and destination language as english. Then Google translated it for me.  Cool na?? 🙂

How to redirect voice from your microphone to your speakers.. It’s cool


You ever wanted to sing on a mic?? I did, but I was (am!!) too reluctant to do so in a public stage. Aah, so in fact I never did it..  until..

So now we are going to redirect the voice from your microphone to your speakers. Sounds cool na? And no additional software is required.

  • Right click on the speaker icon in your system tray.
  • Select ‘playback devices’ >> ‘Speakers’
  • Choose ‘properties’ >> ‘Levels’
  • And then unmute the mic symbol (if there are two mic symbols, unmute ‘front mic’) and increase the volume

Now plug in your mic (or the mic jack of your headphone) and turn up the speaker volume….

… and rock the walls.

[ The configuration instructions are based on windows vista, hope it will be easy to find them in xp too, if you encounter any problem, let me know.. ]
