hello, lately i have problems with any kind of VR content with firefox. A-Painter doesnt work and i cant play any VR video looking a bit around on the internet and trying to change VR related settings in about:config gives me 3 unsatisfying results (trying to play a VR video) : - either nothing happens, the video starts playing normaly in 2d mode and when i press the VR icon the videos pauses but doesnt switch to Vr mode - it starts steamVR for no reasons (which doing the same action didnt start steamvr before, instead the video would just play in VR) but then nothing more happens, juts steamvr is open but the video dont play - i get an error message saying i need a webVr compatible browser i have tried tweaking nearly every VR releated setting in about:config to a point where i dont remember what all the original configs where but i cant simply reset my prefs.js file as this would mess up every other tweaks i have made in my config. trying to play the same video works just fine in MS edge no hardware changes have been made to my pc and i didnt install any new addon to firefox. i hadnt used my VR headset for some weeks so i dont know exactly since which firefox update the issue started. Occulus software is up to date as my other drivers (i didnt update any driver lately neither) are actually up to date or the same as they where when everything worked. i have also tried with a fresh FF nightly install without succes (in nightly i didnt change anything in about:config)
