Use Firefox plugins with any version

Posted on June 29th, 2008 in Firefox, Howtos by Rodney

After upgrading to Firefox 3 (which I love, btw), I have been troubled by the use of my old extensions.

Being a web developer, I miss some of my old plugins for validating HTML and I really missed the snipshot plugin, which is so handy for quick image resizes.

So here’s how you can set Firefox to ignore the plugin version and just use it with your updated install:

  • Type about:config into Firefox’s address bar and click the “I’ll be careful, I promise!” button.
  • Rich click on the white background that comes up, anywhere you like.
  • make a new boolean, called extensions.checkCompatibility.
  • Assign it to false.

That’s pretty much it. You just restart Firefox and your old plugins should be back. If you have problems with any of them… well then, I guess you need to get updates for those plugins or find alternatives; however it’s pretty rare to have problems with common plugins, even when doing the above.
