I've been trying to set up openvr on firefox nightly. chromium and sketchfab work just fine, tracking is smoothly and I can see the preview on my monitor as well as on my headset. In firefox, I only see a grey and white checkerboard on my monitor and the video on my headset is very jerky - as if there is a tracking problem. I've tried the official mozilla VR tests and they work just fine. I've set the flags in about:config and set the path for the openvr dll. I even refreshed my settings. It'd be nice to use firefox since the chromium build is not really a full web browser, it's missing a bunch of APIs and doesn't play a lot of video content. What can I do to improve this? Thanks, Allen
