Make Old Extensions and addons Compatible with Firefox 3.5

So, I’ve had some more time to play with the latest build of Firefox, and I liked it so much that I couldn’t use the 1.5 version anymore. And this left me with a problem: hardly any of my extensions were compatible with the latest and greatest Firefox version.

I’ve made a bit of a research out of it, and here we are: I present you with the 3 ways to make extensions compatible with Firefox 3.5

1) Making Extensions Compatible – THE EASY WAY

All you have to do is to go and download a wonderful Nightly Tester Tools extension. Not only it is compatible with your newest Firefox version, but it will also add a button to your Extensions manager (Tools->Add-ons):

Just click this button and restart your browser. Please note that this is a screenshot taken AFTER making all the xtensions compatible – so as you can see they’re all active already.

The advantage of this way is that it’s really easy to make all your extensions compatible with any Firefox until Firefox 3.0 (that’s what this extension puts as the MaxVersion for each of the extensions it fixes)

The disadvantage is that there is no equally easy way to revert the changes, so once “made compatible”, your extensions will stay this way – there is no button to make them uncompatible again. However, disabling the extension seems to restore the versions.

2) Making Extensions Compatible – THE FIREFOX GURU WAY (pre firefox 3.x)

What you can do is open the configuration (about:config) in your Firefox browser, right click the list and create a boolean extensions.checkCompatibility option there. Set its value to false and restart the browser.

Most of your extensions should work now. If you go to the Add-ons dialog, it will look like this:

As you can see, extensions which would otherwise be incompatible, are flagged with the exclamation mark. You can also see a warning message which suggest you enable the compatibility check again.

The advantage of this approach is that it’s really simple to make the change which affects all the extensions.

The disadvantage is that this way can be used as a temporary solution only, as it may lead to unpredictable consequences (some really old or really new extensions may malfunction).

3) Making Extensions Compatible – THE HARD WAY

This is essentially a manual way of accomplishing the result of using the Nightly Tester Tools extension.

The advantage of this way is in total control over which extensions you’ll hack to become compatible.

The disadvantage is in the fact that every step of this method is rather hard: distinguishing extensions to make sure you’re changing the one you really want, and
manually changing the versions supported.

  1. Close your browser
  2. Go to the folder with all your Firefox extensions:
    C:\Documents and Settings\USER\Application Data\Mozilla\Firefox\Profiles\PROFILE\extensions In this line, USER is to be replaced with your Windows login, and PROFILE will be the name of your Firefox profile (weird looking folder name, usually the only one found in Profiles folder)
  3. You’ll see a list of folders there, 1 folder for each extension. The names of the folders are the unique identifiers for extensions, so they may seem scary at first:
    {34274bf4-1d97-a289-e984-17e546307e4f} – this is the Adblock extension GUID.
  4. Go to any folder, and open the install.rdf file for editing with your favorite clear text editor. Notepad works, but using it will make things even harder cause it doesn’t part rdf files properly. Your choice :) Now back to the business. You need to look for 2 things:
    • name of the extension, to make sure you’re editing the right oneJust look for the em:name, and try to recognize the extension from the description that follows:

      <!– Front End MetaData –>
      <em:description>Filters ads from web-pages</em:description>
      <em:creator>The Adblock Crew</em:creator>
      <em:contributor>Henrik Aasted Sorensen</em:contributor>

    • a block of minimal and maximum Firefox versions the extension will work on.
      Warning: there could be few similar blocks with versions, so make sure you’ll edit the one which has EXACTLY this em:id, the one which belongs to Firefox browser: ec8030f7-c20a-464f-9b0e-13a3a9e97384.
    • <!– FireFox –>

  5. Edit the maxVersion parameter (shown in bold to make it easier), and change it from 1.5 to 2.0b2.
  6. Remove the extensions.cache file from the C:\Documents and Settings\USER\Application Data\Mozilla\Firefox\Profiles\PROFILE\ folder – this will make sure Firefox will read all the changes from install.rdf files and pick up the now “compatible” extension
  7. Restart your browser, enable the previously disabled extension you’ve just edited
  8. Restart your browser again to activate this extension
