Since upgrading windows N with the windows media pack, Firefox immediately crashes on opening various different websites - mostly video ones (Netflix, any youtube.com/watch...) but also mozilla support. Prior to installing the media pack, youtube videos would play but Netflix would not (but no crashes).
Problem persists in safe mode, with DRM content allowed and not, and with hardware acceleration disabled. Flaser player and video drivers are installed and up to date; Microsoft Silverlight is also installed.
Most recent crash report IDs are:

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.Read this answer in context 👍 1

- Flash player, obviously
prior to media pack, gifs/videos would not play on twitter, imgur etc. but now do work fine (and not cause crashes)

That worked perfectly, thanks! When you say it's a workaround, do you mean it shouldn't be used as a permanent solution?
Either way, thanks for the help! Nick
according to the info we got from microsoft this may be fixed through the next major spring feature update (1903?) - you could try to toggle back the preference to its default value afterwards...
the preference shouldn't make to much of a difference anyway during normal browsing anyway, so you could also treat it as a permanent "workaround" too :))
