Hello, I installed Firefox on my Chromebook using the Debian installer. I was able to right click the installer and click install. It's worked really well so far, but the only issue I'm noticing is that MP4 files have no audio and I cannot unmute them. The video plays fine, it's just set to mute and nothing I do will unmute it, including right clicking the video and toggling mute. An example video that will play, but there is no audio: https://html5videoplayer.net/html5video/mp4-h-264-video-test/ To be clear, YouTube videos play just fine through Firefox, and the above video video plays fine in Chrome or even via Discord (which I also installed the same way, using the .deb file). I'm guessing it's an issue related to Linux (maybe there's a codec that isn't available?), but if there is a solution that anyone knows about I'd appreciate it!
