Upgrading to Firefox 3 – and keep your loved extensions

After doing the long awaited upgrade to Firefox 3.0 I realized, that most of extensions would no longer work.

Of course, you might say, they are not compatible with FF3 … that’s true, but does that mean, I have to say goodbye to long trusted fellows? No!

There is a tweak for Firefox, which will allow to keep those extensions:

  • Type about:config into Firefox’s address bar and click the “I’ll be careful, I promise!” button.
  • Right-click anywhere. Choose New>Boolean. Make the name of your new config value extensions.checkCompatibility and set it to false.
  • Make another new boolean pair called extensions.checkUpdateSecurity and set the value to false.
  • Restart Firefox.

Well, this doesn’t make all extensions available in FF3, but at least you can get extensions to work which have been disabled because of the newly introduced security features of FF3.
