Where can I find FF 3.01? My users have 3.01 and my software is not running correctly on the latest FF versions.

My Javascript/HTML code works fine on my Ubuntu box with FF 3.6 but the clients have to use FF 3.01 (compatibility problems with other software preclude them from upgrading to a new FF version) and the software is not working.

Without having access to FF 3.01, I can't debug the software.

I've been unable to find FF 3.01 for Ubuntu. Where can I find it?

See Install an older version of Firefox

If you are going to use Firefox 3.0, you should try the last version 3.0.19 rather than 3.0.1
