Let Older Add-Ons Work With Firefox 3.0 164

Posted by kdawson from the not-for-the-faint-of-heart dept.
mask.of.sanity informs us of a hack that allows old add-ons to work with Firefox 3.0. Short form: in about:config, create a new boolean and set extensions.checkCompatibility to false. "The fix, which requires a little boolean creativity, great for anyone not afraid of taking risks. The idea is to stop Firefox checking its version history, allowing defunct extensions to work... [Those who do] get the fix working will have to remove the code from the prefs.js file once the stable Firefox comes out, but will enjoy their [favorite extensions] in the meantime."

      While it may cause breakage its a great way for users of the beta and RC version of Firefox 3 to get some fairly major extensions work.

      I need IEtab to get certain work pages to work and I really love stumbleupon... So when Firefox 3 upgraded automatically to RC1 and these broke it was quite annoying so i disabled the check.

      An example of an extension this wont fix is Google Browser Sync. You will need to disable this in Firefox 3 otherwise you WILL see some major breakage if you disable the check.

        Odd, IE Tab is working fine here on FF 3 RC 1 without any modifications. That said, I find a safer way to get your favourite extensions working is to edit the version number in install.rdf which is inside the .xpi file (xpi is just a renamed zip file). That way when the extension updates normally, the hack doesn't stick around ready to break something later.

        While it is fine to disable the compatibility checking, my concern is that if enough people disable it they might start expecting the Mozilla devs to actually implement workarounds to 2.0 compat problems in v3. That way leads to many, many problems. Just ask Microsoft.
      • Did you uncheck the "Warn me if this will disable any of my add-ons" box that is on by default? Because FF shouldn't have installed the update if it saw that your version of IEtab was incompatible with RC1 without asking you to ignore the incompatibilities.

      This isn't about making extensions compatible, it's about forcing Firefox to allow you to use extensions that claim not to be compatible, but very well might be. Major breakage certainly could occur, but I find it worth the risk. Many extensions that I was using with beta5 claimed not to work in rc1. Forcing them to load anyway has been very helpful, and they have all worked perfectly without causing any problems (as far as I can tell).

      While I planned on waiting until Firefox 3 is released before switching, I found it preinstalled in Ubuntu 8.04. So I'm using it. I do think that Ubuntu made a bad decision by including a beta web browser, I understand why they did that. The problem is not that the Firefox betas and RCs are buggy. The problem is that misuse of the term beta has led people to expect no less from a beta than from a full release. Gmail has been in beta for years, and it is [arguably] the most complete, feature-rich webmail available. How long was ethereal beta? 10 years? It was pretty stable for at least the past five years, at least, no less than any other full release software. Beta has become a marketing term for "new".

      In the same vein, shouldn't extension developers follow the Fx beta stages so that users will actually switch to 3.0 once it is released, instead of having to wait for months until their plugins have left beta stage?

      I use about 10 plugins since Fx 1.0, and have yet to encounter a single crash due to an extension (the only plugins that crash my browser are GCJ and Flash). Disabling compatibility checking has been a blessing for me, because it means I can use the latest version of Firefox and still use all extension that I don't want to browse without.

    However, as is to be expected with major version changes, lots of API's will likely have changed, so if the plugins happen not to crash outright, they might fail in subtle ways that you don't discover until it's much too late.

        I agree about the singlethreaded thing. Apart from that: no, extensions can't run in some kind of VM. If they did, they would not be able to modify the browser in interesting ways (as this in many cases needs r/w access to internal browser state; this would not be available if you run it in a "sandbox" or VM.

Now, you could say, modules should not be able to crash the kernel, right? Well...if you could limit the interface between kernel and modules in such a way that modules would probably run about 5x slower, needs twice the amount of code to write *and* be unable to do a lot of things that would be interesting because the strict interface does not allow this, then yes. If we don't want to make that sacrifice (and in fact we don't), the smarter way is to only allow modules to be loaded that are actually at least compiled against the correct kernel version.

You can't run both simultaneously (not sure why) and Firefox will check for compatible updates to add-ons after starting a different version (for instance, start 3.0, close it then start 2.0 and Firefox will insist on looking for

    Well, I've been using this pref since the early days of Minefield. I find that most extensions I use work fine under Minefield. Here is a list of them:

    • Adblock Plus
    • del.icio.us
    • Fasterfox
    • Flashblock
    • Greasemonkey
    • Live PageRank
    • NoScript
    • Web Developer Toolbar

    One thing to note, though.. I think recently the mozilla addons site has been changed, and the button to install is now disabled if you use a not-officially-compatible browser version.

    To overcome this, I first install NoScript (it's compatible with Minefield), and then blacklist the mozilla addons site, so it will not run the javascript that disables the button (yes, it's javascript). Then I can install whatever I want.

    Of course, I had a few problems with some extensions. Turned out they really were incompatible, but from my personal experience, most of them work just fine under Minefield.

    • There's an easy way to get around that. Click on the 'Older Versions' link, then just save to the desktop. I do it by highlighting the hard link to the extension and wget'ing it.

      Then, to install it, just open up the Tools>AddOns box and drag the extension into it.

    Not true. There is highly visible UI in the Firefox 3 AddOns Window which lets you to turn compatability checking on again.

  • This is a weak idea for a story, the same advice is commented on somewhere with every new Slashdot post about Firefox releases.

    Better advice would be to go check the Addon's web site and see if there's a beta version that been tested with the new Firefox release. Many of these extensions are written for free and have donate buttons on the site. If you donate to the author, he may be more inclined to "fix" your favourite extension to ensure compatibility.

    Far better than making your browser unstable!
  • Dumb dumb dumb. Most of the popular extensions have beta and dev releases that are compatible with ff3. IMHO, it is better to monkey around with the dev release and maybe get bugs fixed than just live with a mostly broken "compatible"ized extension hoping that it will be updated by the time the official release comes out. THIS IS WHAT BETA (and RC's now, I guess) IS FOR!
  • Most uncomplicated extensions will work fine with the new Firefox. The reason that all will fail by default is that ALL extensions must have a string stating which versions of Firefox they are compatible with -- so when a new version of Firefox comes out, the developer must test their extension, and modify the compatibility number.

    For most extensions, it's as simple as changing 2.0.+ to 3.0.+ or something similar and it will work fine.

    BUT there may be minor code changes that require a partial rewrite of

  • I could have submitted this story any time in the last few years (ever since I found out about the setting in 1.5 or 2.0 betas) and gotten on the front page of Slashdot. And I thought it was common knowledge!

    I would recommend Firefox Portable if you want to see if FF3rc1 is right for you. No registry changes and it allows you to add your extensions without issue. I have 10 add-ons that I use with Firefox and last time I tried to do a blind upgrade with forced add on use Firefox would not even start.

    I just installed Firefox 3.0 this week. I'm generally happy with it, but is there a fix for the horrible location bar auto-complete yet? My jaw dropped when I saw it pop up... what an ugly, ugly, feature. It seems like a pet change of the creators, too, so they don't have any option to turn it off in about:config.
