Firefox won't save tabs.
I can no longer save tabs when I go to exit firefox. For some reason I can't restore previous session from the history menu and there is no restore session button on the default home page. I've also gone to about:config and made sure that 'browser.tabs.warnOnClose', 'browser.warnOnQuit', and 'browser.warnOnRestart' were set to true but nothing is working. I still only get the warning that I'm about to close tabs, but not the option to save them or not.
And I don't want to change the default settings to show previous tabs and windows on start up because I like firefox starting up on the default page, unless I needed to save tabs. Anyways, when I tried that option last it didn't seem to work.
I'm using firefox 4 on a macbook.
Apologies OP...I meant to reply to a different question.
Try this solution for fixing your user settings back to default (in case something got messed up along the way). Reset Config in Safe Mode
