As the title says. In several recent versions of Firefox on Mobile, the media playback is broken in the way that every few seconds there's a small "lag" (distortion) in the audio. It happens with any audio on any page, including audio in a video. lt is also worth to mention that I use Bluetooth headphones (Pixel Buds Pro 2). Other browsers (Chrome, Brave) do not have this issue. I can't figure out in which version it broke.
