Make your old extensions work in Firefox 3.5/Firefox 4

firefox35-logo This is actually an old trick but with the availability of the new Firefox 3.5, this needs to be refreshed. You can force old extensions to work with newer versions of the browser by disabling the compatibly check Firefox performs before each install. To do this follow these steps:

  1. Type about:config into the address bar and click the Agree button.
  2. Right-click anywhere and choose New>Boolean. Name the new config value extensions.checkCompatibility and set it to false.
  3. Make another new Boolean value and call it extensions.checkUpdateSecurity and set the value to false.
  4. Restart Firefox.

Remember, that this might lead to unexpected behavior with addons that aren’t compatible with Firefox 3.5.

Update: To make old extensions compatible with Firefox 4, do the following:

  1. Type about:config in the address bar of Firefox 4. Right click anywhere on the new window and select New > Boolean.

  2. Name the new config value extensions.checkCompatibility.4.0. Set the value to “false”.

  3. Restart Firefox

If you don’t want to do this, which is wise, you can check out this list of addons that work with Firefox 3.5 that Cnet.com prepared so meticulously.
