Firefox crashes after upgrading Windows 10 to 1809

Skrevet

Since upgrading Windows 10 to latest 1809 Firefox has started to crash tabs when I go to e.g. Youtube, but even it will crash when I go to support.mozilla.org. So right now I'm using Chrome to even write to support question.

I have tried several things like: turning off addons turn off flash entirely reinstall nvidia drivers

None of it does something. At first I thought it has something to do with video but Twitch works, while Youtube doesn't, nor does Netflix. And some websites such as this support website doesn't work either without crashing the tab.

I've submitted the crash report and it can be found here https://crash-stats.mozilla.com/report/index/721551db-732a-4017-bfca-b291f0190211

hi ganmo, yes unfortunately this kind of issue is a problem for users of windows N editions after the update to windows 10 1809 & installing the media feature pack.

this would be a workaround to avoid the tab crashes: enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named media.wmf.vp9.enabled. double-click it and change its value to false.

this just disables support for a particular video codec, so you shouldn't experience any performance impact on day to day browsing.

microsoft's analysis of the issue indicated that the issue might go away with the next monthly windows 10 update which should be happening within the next couple of days. you might want to check back afterwards and toggle the media.wmf.vp9.enabled preference back to true and see if the crashing issue is still resolved afterwards...
