How to enable all extensions in Firefox 2.0

You probably already tried the new Firefox 2.0 web browser already and most of you are probably liking what they see. Its feature set is impressive and includes anti-phishing enhancements, a built in spell checker, the ability to restore sessions and to undo closed tabs are all great and helpful. If you ran extensions in Firefox 1.x and upgraded to version 2.0 you may have noticed that some of your extensions have stopped working.

Hans Schmucker, a commenter on my initial article about the new Firefox 2.0, pointed out that you can use an extension called Nightly Tester Tools to make the majority of extensions compatible with Firefox 2.0. Most authors of extensions define a range of Firefox versions that their extension works with and 2.0 is obviously not included in many extensions.

Download Nightly Tester Tools and install the extension. Restart Firefox afterwards and click on tools then add-ons. Hit Make all compatible and restart Firefox again. All extensions should be working fine with Firefox 2.0 now. Some might not be working due to incompatibilities. If that is the case deactivate all extensions again and activate one by one to see which ones are causing troubles.

If everything worked out you are ready to use Firefox 2.0 with the majority of extensions. All extensions that I'm using for instance are working fine with 2.0, for example Adsense notifier, Video Downloader, Download Statusbar, Google Toolbar, Linkification, Screen Grab and many more. Let me know if you encounter extensions that are not working.

Update: Firefox 2.0 has been retired by Mozilla, and newer versions of the web browser are now available for download at the official Mozilla website. The latest version at the time of writing is Firefox 12 (May 2012) with new versions of the browser released every six weeks.

Mozilla made a clean cut from Firefox 3 to 4, and Firefox 4 to 5. Those were the major steps that changed some of the browser's underlying technologies, and resulted in some add-on incompatibilities and changes to the browser's interface.

The company changed add-on compatibility as well in recent versions so that it is no longer necessary to run Nightly Tester Tools to force compatibility.

    yeah, that's one great tool. there used to be some issue running it under linux, but the guy fixed it recently, so there's no reasons not to use it now :)

    I tried it. I made everything compatible. That crashed Firefox. I couldn't reopen 2.0, so I restarted 1.5, then closed it down and was able to restart 2.0. Disabled it all in 2.0. Restarted 2.0, then made two extensions compatible (all-in-one sidebar and Restart Firefox). Now, Firefox 2.0 does not want to start at all.

    Seems to be working now, but somewhat erratically.

    I have been using Bon Echo for about 2 weeks now. After first loading it, like everyone my exts or themes did not work.
    I added the nightly tester tools from this site:
    http://users.blueprintit.co.uk/~dave/web/firefox/nightly/index.html

    after installing restarted Bon Echo and then made compatiable the exts and themes that I had and restated once more and vivola!!! All is working. Over the past 2 weeks I have used Bon Echo with no problems. Usually everynight there is some updates for Bon Echo but in the morning everything is still working like a champ!
    The new spelling and anti-phishing tools also work out quite well.

    Myself I can wait until the Offical Relase of 2.0... I'm not in that big of a hurry right now and I never liked "Beta Testing"... hehe

    I have been using Bon Echo for about 2 months now and have been waiting for something like this. Thanks.

    If you want to test things out in a sandbox, download the Portable Firefox, then run it straight from the folder.

    Since it keeps all of its data in that folder, it won't mess up any of your 1.5 settings.

    You can add the extensions you want to test one at a time, and build up that way. If you have a habit of downloading your XPIs and installing them manually, this ought to be an easy process. (You DID know that you could drag and drop a XPI onto the browser to install, right?)

    Been running 2.0 Beta 1 since announced and works great. Nightly Testing Tool in my Add-Ons (f.k.a. Extensions), since a long time to bypass the version numbering install restriction. Gradually force installing my 62 odd add-ons....All-In One Sidebar sofar causing Status bar to become hi-rise hi, so on hold. The Force installing for each causes the freeze of the Add-On window, but killing FFx and its great sessions recovery and sublime speed its gained in restarting make it an acceptable Beta Pain.

    After installing Firefox 2.0, I acknowledged the warning screen that said many of my old Firefox extensions wouldn't work with this beta version. What I didn't know is... they are deactivated even when I switch back to version 1.5! I've since deleted Firefox 2.0, but can't get my old functionality back. Any tips?

  14. Martin July 17, 2006 at 8:17 am #

    You will have to activate them again in the extensions menu.

    is not available for Linux.

    :-(

    Help me please...
    I just installed Firefox 2.0, and all of a sudden, my username/password isn't being inserted in the signon window (it always was before). I tried the usual suspects--I did not mistakenly tell FF not to remember the password for this site; and I also tried the remember password bookmarklet, but all to no avail--FF will not ask me to remember this password. What do I need to do to get around this?
