Run multiple Firefox instances/versions at the same time

Here is a quick tip for ya. To run multiple instances of Firefox at the same time, do the following.

Firefox Profile Manager

Linux

1. Run this command in Command Terminal : firefox -p -no-remote

2. The Firefox profile manager will open and ask you to choose the profile you want to use. If you already have more than 1 profile, click on the “Create Profile” button to create a new profile and once the new profile is created, select it and click “Start Firefox”

3. That’s all.

 

Windows

1. Open run prompt by pressing Windows key + R

2. Run this command in run : firefox.exe -P -no-remote (NB: -P is in CAPS)

3. The Firefox profile manager will open and ask you to choose the profile you want to use. If you already have more than 1 profile, click on the “Create Profile” button to create a new profile and once the new profile is created, select it and click “Start Firefox”

4. That’s all.

 

You can also edit the Firefox short cut in your desktop, quick launch (Windows) or panel (Linux) and add the text -p -no-remote to it, so that each time you open Firefox it will ask you to choose the profile you want to load.

 

What is this good for?

1. You can sign into multiple Gmail accounts (or other accounts for that matter) at the same time (One in each Firefox instance)

2. You can run multiple versions of Firefox at the same time. Just create a separate profile for each version and choose the correct profile when opening Firefox.

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

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

colorfultabs

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

measureit

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

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

1337

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.

Retrieve flv videos (and other files) from firefox cache.

Yesterday my friend sent me a link to a video in his site. I saw the video as streaming and I liked it. I just wanted to keep a copy of it in my collection. So as usual I went to keepvid, my favourite YouTube grabber site. But I couldn’t download the video because the site was not supported. Well these grabber sites do not support the majority of the streaming video sites, coz they are so many of them using different encoding  methods. It was then I thought of it – prior to playing the file, firefox (or any other browser) keeps a copy of the video in its local cache. So I googled to see if there is an option to save cached files, and came up with these..

Tool: Go to http://www.nirsoft.net/utils/video_cache_view.html, there you can download ‘Download VideoCacheView’. This tool will allow you to see all flv videos in your cache..Remember again – you can browse only flv videos using this tool. It is a freeware.

Screenshot

Or click here to download the file directly.

Trick: Ok here is a neat trick to save any file from your cache. If you are using firefox, in the address type about:cache and hit enter. The resultant page will display various information about your cache. On that page click on the link List Cache Entries, and you will get a detailed list of all files that are currently in firefox cache. If you want to save any of those files just browse to the cache folder – it is given at the bottom of the first page (about:cache). It looks something like this 'C:\Documents and Settings\copzz\Local Settings\Application Data\Mozilla\Firefox\Profiles\j1l44nro.default\OfflineCache'. Now browse to this folder and copy and save the file you need into another location and change its extention to whatever it is, like .jpg .flv etc.

And you are done. Happy caching.
