Firefox 4 Back, forward, refresh buttons not working
Upgraded to Firefox 4 yesterday. Had problems navigating as the back, forward, and refresh buttons would not work. URLs would also not show up at times. Reverted back to 3.6 and now no issues. Anyone else having this problem?
In that folder, send the file called prefs.js to your recycle or trash bin. Then restart Firefox. The buttons should work correctly -- at least they did for me.
If you find it is too troublesome to lose the preferences, you can restore the file from your computer's recycle or trash bin. Be sure and do this when Firefox is NOT loaded as it overwrites the pref.js file when it closes.
I keep a list of changes that I make to the preferences file for all our systems, so resetting these was not a great burden. I found it rather worse not to be able to use the BACK button.
I noticed that my preferences file was loaded with obsolete settings from uninstalled extensions that did not clean house when leaving. Perhaps it is better to fumigate the preferences to keep this from happening again.
Before discovering this, I messed around trying to change obvious settings, such as those associated with history, to no avail. I also uninstalled all the existing extensions, also to no avail. This solution got it working again. Oddly, I only had this problem on one of our six systems.

I tried the solutions that dealt with prefs.js, and they did not work for me; however, I found a solution on a different web site that did work. I had installed McAfee SiteAdvisor (as I always do) after installing Firefox 4, and that was causing the problem. Disabling SiteAdvisor fixed the problem on my installation of Firefox 4.
