Firefox 4.0.1 seems a disaster. Ever since I downloaded it (using Vista Business) Google is useless, and other search engines also freeze up or refuse to scroll. Is this a common problem. Should I go back to Version 3.6, and if so how do I do it?
Many thanks to Robinofloxley. I used Filehippo to go back to Firefox 3.6.17 and it worked perfectly. All my bookmarks remained intact. The problems were only with the search engines, which always froze, and were impossible to open or close down. Each time I needed to use the Task manager to close the program and start again. I will wait a few months and read how Version 4 is improved before I try it again.
