Whenever firefox is started, it will always open to all of the tabs that were open in the previous session. No matter what I do, firefox will always, ALWAYS do this and does not seem to be able to stop. I have: -Gone through the options and set firefox to open to the home page/blank page. -Re-installed firefox -deleted the session store files on my computer -Gone through about:config and set the values for browser.sessionstore.max_tabs_undo, browser.sessionstore.max_windows_undo, browser.sessionstore.max_resumed_crashes, and browser.sessionstore.resume_from_crash to 0 and false respectively None of these options have worked and firefox is still loading up all previously closed tabs regardless of the changes made. I have a windows 7, the latest firefox, avast! Antivirus, blue coat k9 web protection, and the windows firewall. Any ideas would be greatly appreciated.
