Currently I am using Firefox 7.0.1 (the most current version of Firefox).
Today I opened and used Firefox 3.6 for testing purposes and I did not move the application to the application folder, I just double clicked it to open it. After closing FF 3.6, I reopened FF 7.0.1 and I noticed something very strange, all of my browsing history are gone and AdBlock was gone too, luckily bookmarks are still intact. I am sure something conflicting is going on, how can I restore the settings and the browsing history of FF?
I am using Firefox on a Mac.
