Rated 5 out of 5 stars

Following Rezwan's excellent suggestion on March 25, 2010
I modified the v0.5.7.5b2 and it works excellent and restores all the functionalities of GMail manager as before.
Most of the following suggestions are taken from Rizwan's message. So all credit to him!

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. Keep the window open.

3. You should see a "install.rdf" file. Open Notepad; Drag and drop install.rdf into Notepad.

4. Find tag and replace "0.5.7.5b2" with "0.6.3".

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

6. Save the file on your computer hard drive (eg; desktop), make sure the file name stays "install.rdf".

7. Drag the saved rdf file back into the WinRar window. Accept replace old file.

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

THANKS A MILLION RIZWAN.
