Firefox 43.0b1 cant play videos anymore
Since updating firefox I noticed that it started to have issues with playing videos.
First I noticed that the videos that I think aren't vp9 stopped playing on youtube. first I started blamed google for this but noticed that videos on NBA.com and ESPN stopped playing as well so it must be something wrong with Firefox.
one more thing I don't have flash installed
So can this issue be fixed ??

You can check the prefs.js file in "Old Firefox Data" folder on the desktop (if you kept this folder) to see if there are media prefs listed that might have caused this.

Sadly I deleted them, I was angry and was thinking about switching to chrome. however I had costume preferences that allowed vp9 playback
media.mediasource.ignore_codecs
media.fragmented-mp4.exposed media.fragmented-mp4.ffmpeg.enabled media.fragmented-mp4.gmp.enabled
media.mediasource.webm.enabled media.mediasource.enabled
I had this enabled plus i was forcing hardware acceleration. however this is the first time firefox stopped playing videos and was giving me errors like Video can't be played because the file is corrupt and No video with supported format and MIME type found
I even tried to downgrading firefox sadly no go so I ended up refreshing it however I have not enabled vp9 support or hardware acceleration yet

If you make such changes to prefs to enabled feature that may not be supported properly then that is at your own risk and you have to remember that you may have to undo these changes in case of problems. In severe cases where you can't start Firefox you need to edit prefs.js or create a user.js file to override defaults.

Well I re enabled all of this after refreshing FF and it works. I don't know what happened there
