Firefox 3.0, How To Make Old Extensions Work

Posted: November 20th, 2007 | Author: RyanN | Filed under: HowTo, Tips | Tags: | View Comments

Firefox 3.0 beta 1 is out. As with previous releases of Firefox, the new version number breaks your extensions. Here’s how to fix them.

  1. Open about:config (don’t mind the new roadblock)
  2. Right-Click the list and create a new boolean ‘extensions.checkCompatibility’, set it to false
  3. Restart Firefox

Update: This does not appear to work on the beta 4 release.

    Well done!

    I too like the option of mouse gestures in my browser.


    Thanks again.
