My tabs are crashing (Gah. Your tab just crashed.) Windows 10N
I was getting errors while playing youtube videos : "Your browser does not currently recognize any of the video formats available"
I tried disabling addons and a bunch of other things that I saw googling through the error. I eventually uninstalled and reinstalled firefox to see if a clean installation would work. It didn't. I saw next someone mention that it might be a windows media issue and since I have Windows 10N I've had to download the Windows 10 Media Feature Pack before for something. I tried to download and reinstall that. Since then, it's gotten worse. My tabs how completely crash if there's any video on the tabs. They also possibly crash for other reasons, but I'm not sure (when I go to pages where I don't think there's any video, but who knows.
Crash report: https://crash-stats.mozilla.com/report/index/455b90e2-a0ed-4182-859b-78d610190217
It seems like there's something wrong with msvp9dec.dll, which seems to be a Windows file. I'm not quite sure what it is or what to re-install to fix it.
Any help would be greatly appreciated. Thanks!

hi, this should 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, then restart firefox once.

This is a recent bug. Microsoft and Mozilla are working on the issue. From Bugzilla;
All crashes have the signature Ndr64pClientInit with crash reason EXCEPTION_ACCESS_VIOLATION_WRITE.
I went backwards in Firefox versions from 65 all the way to 50:
Versions 56 and newer are crashing Versions <=55 are working

Thanks for the tip. I tried a System file check. It did find corrupt files and repaired them, but it has not solved the issue.
Instead of downgrading to an earlier version of Firefox, I'll use Chrome instead until the issue is resolved. Thanks again.
Sorry about that. But at least you fixed your system files.

This worked!! Thanks, very much appreciated. I'm assuming I'll be able to turn this back on once it's fixed?
