Downgrading to Firefox 3.6 can cause problems with extensions. You need to go to your profile folder and delete the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite. Deleting these files will force Firefox to rebuild the list of installed extensions and checking their compatibility.
For details of how to find your profile folder see https://support.mozilla.com/kb/Profiles
I did what you said and i am still having the same issue.
Try "Reset all user preferences to Firefox defaults" on the Safe mode start window. That will also restore your corrupted user agent (Firefox/3.0.11)
