Firefox tab crashes when opening Mozilla Support page, Youtube videos and others.

Posted

Good evening !

After reinstalling Windows 10 1809 properly on my computer (total reset), Firefox is unable to access some websites and content such as Mozilla Support page or YouTube videos:

Some details :

- It does'nt happen with other web browsers (tested on Chrome, Edge and Opera). - Youtube homepage loads just fine, but the crash happens when I click on a video, no matter if I'm logged in or not. - Mozilla homepage works just fine, but support page is impossible to reach (I had to use Opera to write these lines) -I installed Microsoft Feature Pack (this one : https://www.microsoft.com/en-us/software-download/mediafeaturepack), but no improvement. - I tryed to reset the USERAGENT but it was already by default. - I tryed to reinstall Firefox, no improvement. - I have tryed with and without Adobe Flash, no difference, problem is still here.

Here you can see the 7 last error codes found in about:crashes

Here is a couplet of websites that are impossible to reach at all at the moment, but there should be more ... https://www.clubic.com/ https://www.gettyimages.fr/


My Windows is brand new and official, I have a tower system that works perfectly fine except for this problem, which is very weird, that's why I'm askig you some help !

Thanks for your precious help and for your time.

hi guillaume , unfortunately this kind of issue seems to be a problem for users of windows N editions after the update to windows 10 1809.

we are in contact with microsoft about the problem - until there is a fix for the issue, 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.

Hi Philipp

Thanks for your fast answer. Your manipulation worked perfectly fine, thank you !

I'll wait for Microsoft to find a fix about it and reactivate it so.

Thanks again.
