whenever it crashes and i try to reopen the program, it opens all my old tabs and windows. often these are videos which all start playing at once. or worse, it opens the page that made it crash in the first place and crashes again.

how do i stop this annoying feature?

if there's no way to stop it, can you recommend a simple browser that doesn't try to think for you?

Chosen solution

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

That way you see if the previous session didn't close properly or crashed and will allow you to deselect the tab(s) that you do not want to reopen, but will allow to reopen other tabs.

hello, enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named browser.sessionstore.resume_from_crash. double-click it and change its value to false.

THANK YOU.

I've been trying in vain to change this for a long time!

you're welcome!

however firefox ideally shouldn't crash in the first place. if you want to, you could you provide your latest few submitted crash reports and maybe we can find an obvious cause & fix for that: enter about:crashes into the location bar, copy the latest few report ids from there & paste them here into a forum reply.
