Back/Forward page arrows not working.
All of a sudden Firefox, version 3.6.3, will load and operate normally except for the page back and forward arrows. They remain "gray'ed out" and inoperative. I can still use the small down arrow to bring up the list of pages and select which one I want though. So I re-installed Firefox and the arrows again start working as they should. The next day I boot up the computer and starting Firefox brings up the "installing updates" message and an update is installed. When Firefox finally comes up it has the same problem with the arrows as before. This sequence has been performed several times with the same result. I have just set the config file, using "about:config", to not accept updates and hope that this will help. Any suggestions about this problem will be greatly appreciated. Thanks.
