The back button is greyed out and not working, no matter how many pages I go through, on the same tab. Why?
ie the back button doesnt work. I am remembering history, but the back button doesnt seem to know about it.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
- https://support.mozilla.com/kb/Safe+Mode
In Firefox 4 you can use one of these to start in Safe mode:
- Help > Restart with Add-ons Disabled
- Hold down the Shift key while double clicking the Firefox desktop shortcut (Windows)
This can also be caused by a problem with the file places.sqlite that stores the bookmarks and the history.
Corel: You keep posting this all over the place but can't you see it isn't helping people? Safe Mode is useless. I have no conflicts with add-ons, extensions or plugins. Those dozens of "places" files that you say must be deleted...that's utterly insane. Firefox has created a new browser that is buggy in a major league way and they must fix it. If not, I'm going to use another browser and I will uninstall Firefox.
Try going to about:config and change browser.sessionhistory.max_entries 0 to browser.sessionhistory.max_entries 999
mercave's suggestion solved this problem for me. thank you.
