Once firefox crashed on my system. I tried reopening it but every time it would not open and would crash again. I restarted my laptop and opened firefox and tried opening the history tab but it won't open. Basically no new tab would get opened. No add-on was working. I uninstalled firefox and installed it again from the official site and it was working normally. But when i closed it once and tried opening again, the same problem was there. No new tab or bookmarks tab, history tab, options tab would open. Moreover it would not show anything in my history or my saved bookmarks. Now whenever i reinstall firefox, it would work just fine for the first time. But after closing and opening again, it wont work normally. Though sometimes it would show the options menu, history and saved bookmarks but would not open them in a separate tab.
