Hello Firefox Community, I'm hoping for some help with a persistent video playback issue on Firefox for Android. I am committed to using Firefox for its privacy and its independent Gecko engine, but this performance bug is a major blocker. The Problem: When I play videos in Firefox, the playback is very choppy and stutters, appearing as if it's running at a very low frame rate. Crucial Testing Information: This issue is specific to certain browsers. I have tested the exact same videos on Chrome, Vivaldi, Brave, and Ulaa, and they all play perfectly smoothly. The stuttering issue happens in Firefox (and also in Opera). This confirms the problem is with how Firefox is rendering video on my device, not a network or hardware limitation. Troubleshooting Roadblock: I have already tried all the basic fixes (clearing cache, reinstalling, etc.). I attempted to follow standard advice to troubleshoot this by accessing about:config to check the status of hardware video decoding. However, access to about:config is completely disabled in the stable version of Firefox for Android. This prevents any advanced user-side troubleshooting for performance issues like this. My Device Information: Phone Model: OnePlus Nord 2T Android Version: Android 14 Firefox Version: 143.0.4 Given that a critical troubleshooting tool is unavailable, I am reporting this directly. This seems to be a hardware acceleration incompatibility issue with my device. Any help would be greatly appreciated. Thank you!
