If there is a Firefox Extension you use a lot that isn’t included in the list above, please leave me a quick comment with a link to the extension and I’ll review it to be added to the list. In an effort to keep this list as useful as possible, I will only be including extensions that appeal to a large number of people.

My intention is to keep this list as useful as possible, so it will be updated regularly as more extensions become available.

  • Matt Ellsworth

    Great list. I use a few of these – but this has a few more that I don’t.

  • brian

    Firefox Enhanced should be Forecastfox Enhanced. Other then that, great list. I’ll try a few I haven’t installed yet. =)

    Hope someone can help..
    Ive now got Firefox3 but my Google Toolbar has gone so I’ve tried to install a new one but it says b’coz I have Firefox3 it won’t/can’t get installed, the same problem with Fasterfox ??
    Please.. if anyone knows a fix will u please reply here. thankyou.


  • Kyle Eslick


    You’ll want to use the Nightly Tester Tools Firefox extension. With that extension, you can force extensions to be compatible with new Firefox releases.

  • Andrew

    A great list! 🙂 And well, just to add on, I think Cache Viewer should also be included. It ensures you to be able to save any videos watched, or any other files opened in the webpage without fail as you save directly from firefox cache. To me, VideoDownloader does not cover a lot of websites and Cache Viewer becomes another essential extension.

  • Jason

    Thanks Kyle, I’ll give it a try.

  • Jason

    Unfortunately I’m still having trouble with installing the Google Toolbar, I installed the Nightly Tester Tools for Firefox but it still says ‘ it is not compatible with Firefox 3.0b1.’
    Pleeeeeeease, anyone that can help please reply. THANKS VERY MUCH!

    You’ll see I left a msg 4 up from this one.

  • ELoCannon

    Nice one thanks for your hard work 🙂

    You forgot a category for porn:
