Firefox 3 is out, awesome! Oh wait, half my add-ons don’t work now…Garbage. Here’s a simple way to make Firefox2 add-ons run on Firefox 3, even if they have compatibility problems. Basically, you just edit a text file, it’s really quite simple. All you need to do is to save the add-on on your computer and do a little tweaking. Make a small change to the version in the file editor, and the add-on is ready for installation.
