Problem: Firefox crashes on some sites 1. Did latest windows 10 update (did not get a lot of choice) 2. The page "www.onlineluisteren.nl" did not play any stations any more, there was a message in Firefox that I should install something from a Windows media something. 3. I followed the link that Firefox provided me and installed the Windows media something update 4. Since then, Firefox page crashes everytime I visit the "www.onlineluisteren.nl" , it shows up for 1 second and it crashes and gives a Firefox error page. 5. Also other sites (I think with media in it?) crash. For example google agenda works


Here the number of the crashreport: bp-8072f515-d0c6-41ca-8ae3-ca6d70190201

hi, 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, this could be a workaround for the tab crashes in the meantime: 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.
