HOW TO GET 0.5.7.5 ON FIREFOX 3.6:

The solution is simple. Go to this link: https://addons.mozilla.org/en-US/firefox/addons/versions/1320 and download version 0.5.7.5. Once you have the file, change the extension from .xpi to .zip. You can now open this file with any archiving program (WinZip, WinRar, et al). Extract the file install.rdf. Open it with a text editor (WordPad, NotePad). Scroll down to the section labeled Firefox. Find the line that reads: 3.5.*. Change this to 3.6. Save it, then insert this file back into the archive, overwriting the old install.rdf. Rename the archive back to .xpi. Now you can open Tools|Add-ons and drag this file to that window to install the Add-on and voila: you now have Gmail Manager 0.5.7.5 on Firefox 3.6. I'm using it, and it's working great!
