Best Firefox 3 extensions

We generally try to limit the number of extensions we install for security, performance, and because we use a lot of different systems. That’s not to say there aren’t a lot of interesting addons out there and Mozilla has recently announced the winners of their Extend Firefox 3 Contest. Lifehacker has a full rundown of each of the winners. Nothing really stands out in our eyes (although we might try’s toolbar).

The three extensions we always end up installing are Firebug, Greasemonkey, and Flashblock. What are yours?

    I almost always get URL fixer. I’ve typed .con so many times its not funny.

  2. keici says:

    adblock plus is essential for me

  3. jazzman says:

    I type .xom constantly

    I couldn’t live without FoxMarks to sync my bookmarks across systems, and I use AdBlockPlus.

  4. nedim says:

    I use FlashGot, Gmail Notifier, Download Statusbar, and Web Developer! That is my standard set of addons to firefox! I have some other that are disabled until i realy need them! :D

  5. Rich says:

    TamperData is totally crucial.

  6. D says:
  7. Paul says:

    Noscript for blocking urchin.js and those increasingly annoying scripts that prevent you from viewing a page if adblock is turned on.

  8. doug says:

    adblock plus
    colorful tabs
    gmail manager
    mouse gestures (optimoz)

  9. Spoofy says:

    i cant live without foxmarks…

  10. pip says:

    I also use Adblock plus.

    @7: Never heard of that!

  11. Bryan says:

    I always use Adblock Plus Download Status bar and something called Compact Menu Blue, It shrinks down the top menu, and if u use the ifox theme, instead of using an ugly blue logo, it gives you a nice pretty apple button, I use a few others too… but none to important to others to use, like an add-on that turns off the automatic playing of flash files, If I want to view them I click on them and they play. Great For annoying adds that shout in your face when you blaring tunes… you know… the ones that say something g a y like “CONGRATULATIONS YOU HAVE JUST WON…” YEAH RIGHT!

    BTW I run Vista x64 Ultimate on my PC and XP on the laptop… I must say… I like vista, when using more than 10 plug in’s for Firefox… but if using less than that… XP and Vista opens Firefox about the same.

  12. Zach says:

    I generally find myself installing Firebug, FoxyProxy, Hackbar, NoScript, FlashBlock, Web Developer Toolbar, Foxmarks, Modify Headers, Tamper Data, and User Agent Switcher. Greasemonkey usually ends up on some boxen here and there.

  13. yooper says:

    AdBlock Plus, baby!

  14. Wolf says:

    Adblock plus
    disable backspace navigation
    desk cut

    I’ve got a few others but the former are those I find to be the most useful. The last two should’ve been integrated into Firefox by default though.

  15. moloch says:

    download status bar is a must! I hate the standard download screen. I use Adblock Plus as well, great add on.

  16. underdog5004 says:

    adblock plus
    Tab mix plus

    That’s my list :)

  17. 36chambers says:

    Foxmarks,FlashGet,Add2Search Bar

  18. Shadyman says:

    For all you “.com” mis-typers, a shortcut:

    Type the name of the .com you want, for, type ‘cnn’ in the address bar, and press Control+Enter. It adds the “http://www.” and “.com”.

    You can also do Control+Shift+Enter, Shift+Enter, etc.

  19. kholdstare says:

    What about the Google Toolbar? That’s one of the best addons, it has support for multiple systems and navigators, has popup blocker, spellchecking, it’s multilanguage, has search feature, bookmarks and a long etc.

  20. BigD145 says:

    User Agent Switcher
    adblock plus
    pdf download

    But where’s the torrent search?

  21. PocketBrain says:

    Splitbrowser. You can split the browser in half; great for side-by-side browsing of different web pages, especially on those giant, 22″ widescreen LCD’s.

  22. Wwhat says:

    Apart from the usual adblock/noscipt/flashblock and some developer/maintenance stuff I also insist on slimsearch and when at some point I saw it featured tried flagfox which I find to be surprisingly interesting, it adds a little country flag for every site you visit using an internal db and it’s often surprising and elucidating.

    As for google toolbar… I consider it malware just by the way they try to push it alone already.

  23. Fleeced says:
  24. proxy says:

    adblock plus
    download statusbar
    IE Tab
    Save Session

  25. jah says:

    noscript, firebug and tamperdata ;)

  26. kresp0 says:

    My list:

    * adblock plus with all filters
    * tamperdata
    * noscript

  27. Elliott says:

    i allways install googlepeida. it puts the wikipedia article on the right side of the google results page for what ever you were searching for.

  28. Rawrl says:

    Is there one that makes FF3’s interface not suck?

  29. Befread says:

    Noscript,Google toolbar and FEBE are good for me

  30. visionetiks says:

    I can’t believe I am the only one who finds Speed Dial essential…

    It can seriously speed up your daily operation

  31. Aud1073cH says:

    my top 3:
    1) Adblock Plus
    2) Filterset.G Updater (for adblock plus)
    3) NoScript (like flashblock)

    DownThemAll / Flashgot
    Customize Google

    addons from FF2 I wish they’d update:
    Tabbrowser Preferences

  32. JavaNut says:

    I don’t notice addons until their not there..

  33. bruno says:

    Weave (to sync bookmarks, passwords, cookies, tabs)
    adblock plus
    cs lite (with the auto-updated blocklist)
    download statusbar
    url fixer
    stop or reload button
    update scanner (for website without rss)

  34. PKM says:

    Adblock Plus, Mouse gestures and greasemonkey are my indispensible ones. I’ve never come across a site that wouldn’t let me view it with adblock on (and tend to forget that the internet has adverts until I have to go back to IE), but put instructables on the whitelist anyway because aw shucks, they asked so nicely.

    Colourful tabs (or whatever it’s called) is useful at work when I have a lot of google and msdn tabs open to make them stand out from the rest.

  35. Justin says:

    I basically NEED Tab Mix Plus to use firefox. It lets you set it so that tabs can span multiple rows. Right now I have 5 rows of tabs open, 6 columns per row.

    Image Zoom lets you right click on any image and increase / decrease its size using the scrollwheel (and other features)

    IE Tab with the auto-sites filter for sites that just refuse to work in FF

    Forecast Fox – I like it on the top of FF on the same row as the Menus

    Adblock Plus of course

    BugMeNot for random crappy news sites

  36. Ahrenjb says:

    AdBlock Plus, TamperData, Download Statusbar, and l337key are my essentials.

    Wouldn’t know what to do without em!

  37. inuyasha says:

    user agent switcher
    adblock plus
    tweak network
    batch downloader

  38. dinsh says:
