Firefox closes randomly, no error message.

more options

My firefox closes randomly without any error message. When I start it again it either automatically loads the pages that were open or says something like "oops we are having problems restoring your session" and I have to click restore session manually. 99% of the time it happens when I am loading a page. It almost always happens the first time I turn on my computer and open firefox. After that randomly throughout the day when I open a new tabs. It used to happen like 10% of the times I opened a tab, but after I disabled all the add-ons and hardware acceleration it happens like once every 30 tabs or so, but still happens. I have tried reinstalling but that didn't solve it. Using safe mode seems to solve the problem, but disabling add-ons only makes it better, doesn't solve it completely. I don't have an antivirus besides the windows 10 default one.

You said you tried reinstalling but maybe it's something else, and a refresh might fix it? Additionally, is it for ANY website every 30 tabs or do you find its a particular website each time? Or have you not noticed any pattern like that? Either in the meantime, Try this:


The Refresh feature (called "Reset" in older Firefox versions) can fix many issues by restoring Firefox to its factory default state while saving your bookmarks, history, passwords, cookies, and other essential information.

Note: When you use this feature, you will lose any extensions, toolbar customizations, and some preferences. See the Refresh Firefox - reset add-ons and settings article for more information.

To Refresh Firefox:

  1. Open the Troubleshooting Information page using one of these methods:
    • Click the menu button New Fx Menu, click help Help-29 and select Troubleshooting Information. A new tab containing your troubleshooting information should open.
    • If you're unable to access the Help menu, type about:support in your address bar to bring up the Troubleshooting Information page.
  2. At the top right corner of the page, you should see a button that says "Refresh Firefox" ("Reset Firefox" in older Firefox versions). Click on it.
  3. Firefox will close. After the refresh process is completed, Firefox will show a window with the information that is imported.
  4. Click Finish and Firefox will reopen.

Thank you for the reply.

Refreshed firefox, first tab I opened after refreshing closed the browser, so I guess it didn't fix my problem.

It doesn't matter what website I am trying to load. It has and has not happened on sites that I visit more often but it has also happened on pages I have only visited once.
