Its great that you've updated your release schedule and are innovating at such a fast pace.

But youv'e got to remember that you need to provide setup files to all the older versions of firefox for testing purposes. I found an old copy of 3.6.7, I got 5, I will probably get 6 soon when you update it, but I can't find a reliable trustworthy source for firefox 4.

Go to http://www.oldversion.com/Mozilla-Firefox.html Scroll down to Firefox 4.0 Click it. Click the Download Now button. Run the program. NNo need to remove older or newer version of Firefox it will overwrite.

Firefox 5.0 was partially a security update in place of 4.0.2. The 4.0.1 is old and not supported anymore.

For Firefox 3.6 the current 3.6.* release is listed at http://www.mozilla.com/en-US/firefox/all-older.html and 3.6.20 will be there sometime tomorrow. The 3.6.7 is rather old and behind on security updates.
