This might help those (like me) who miss the proper functionalities of Gmail Manager. You can follow the steps below to modify version 0.5.7.5b2 to make it appear like version 0.6.1 and force Firefox 3.6 to use it.

1. Download Gmail Manager 0.5.7.5b2 from http://longfocus.com/firefox/gmanager/releases/gmanager0575b2.xpi [That's the developer's site.]

2. Open the file with WinRAR or similar.

3. You should see a "install.rdf" file. Extract it and open with Notepad.

4. Find tag and replace "0.5.7.5b2" with "0.6.1".

5. Find tags and replace "3.5.*" with "3.6.*"

6. Save the file, make sure the file name stays "install.rdf".

7. Put this rdf file back in the XPI package.

8. Drag the package into a Firefox window. You should have Gmail Manager's much loved functionalities back! ;)

When the next official update is released, FF should be able to install that without any issues. Hope it helps!
