Update: Selenium 1.2.0 is now officially released and supports Firefox 6! Please visit seleniumhq.org to download it now!

Continue reading for the original post where I patched Selenium to work on Firefox 6; however, it’s no longer relevant since Selenium 1.2.0 has been properly released. Continue at your own risk and discretion.

As you probably know, Selenium is an application designed for automating web browsers (primarily to test web applications). Unfortunately due to Mozilla releasing new versions of Firefox like grease lightning, the latest version of Selenium IDE doesn’t work with Firefox 6 yet. The changes to Firefox 6 were mostly for speed and ad-protection, so chances are the Selenium IDE will still work fine. Thinking I have nothing to lose, I went ahead and modded the Selenium IDE version controls so it works with Firefox 6. You can download a copy below.

How I made it work

If you’re wondering how I got this working, Firefox extensions are just zip files. I unzipped the XPI and modified the install.rdf to allow up to version 6. Then I unzipped all the other XPI files (because it contains lots of others) and did the same thing. Then I zipped everything back up properly for installation in Firefox.

This should install in Firefox 6 but I can’t guarantee functionality or support this release. I can say that it’s been working for me, but use at your own risk!
