Firefox crashes quite often, especially when I have multi tabs open. I usually have to use CTRL ALT DEL and end the process as Firefox stops responding. My problem is not the crashing........it is the re-opening of the multiple tabs I had open, when normally it is one of them (not the home page) that caused the crash in the first place, so I cannot re-open firefox until I restart the pc, because every time I do it is the same story. Firefox tries to re-open all of the tabs and stops responding. I have looked in options but nowhere does it allow me to stop multiple tabs opening after a crash. If this continues, I will have to uninstall Firefox and stick to Chrome.

Set the pref browser.sessionstore.max_resumed_crashes to 0 on the about:config page to get the about:sessionrestore page immediately with the first restart after a crash has occurred or the Task Manager was used to close Firefox.

That will allow you to deselect the tab(s) that you do not want to reopen, but will allow to reopen other tabs.

See:


To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.

  • Use the Filter bar at to top of the about:config page to locate a preference more easily.
  • Preferences that have been modified show as bold (user set).
  • Preferences can be reset to the default or changed via the right-click context menu.
