Hi.
I suspect the problem is caused by Firefox's Gecko-based Android media stack.
Device:
Honor Magic V5
Snapdragon 8 Elite
MagicOS 10.0.0.157
Software:
Firefox Android 152.0.6
uBlock Origin the only extension
Reproduction:
Open any YouTube video in Firefox.
Play at 720p or higher.
Pause/resume or seek.
Audio and video begin intermittent stuttering.
Switch to another app and return to Firefox and playback immediately returns to normal without reloading the site.
Comparison:
Chrome: works fine
Vivaldi: works fine
DuckDuckGo Browser: works fine
Things tested:
Hardware acceleration enabled.
Battery optimization disabled.
Performance mode enabled.
Cache/history cleared.
media.android-media-codec.preferred tested.
gfx.webrender.software tested.
AVC and VP9 both affected.
Inner and outer displays affected.
Desktop mode also affected.
Firefox Nightly stutters even without seeking.
