Mozilla has fixed a playback issue on YouTube that affected some Firefox users for several months.
Some Firefox users noticed playback issues on YouTube for several months. These affected high resolution videos only, from 1080p and up. To make matters worse, no clear pattern could be identified.
Some videos played fine, others would stop abruptly when they ran out of buffer.
That's a lot of effort, given how many people I am subscribed to. And I wouldn't say that it' "peanuts", after all they redistribute 55% of YouTube Premium earnings, that's a lot more than what other similar subscriptions give.
Would you support that kind of business model if you were at the other end, knowing full well you could be earning more? Then again, this is an age-old question...
For an slightly better but still degraded experience they want you on Google Chrome. But remember please use 360p or lower so their poor servers don't have to work so hard, they even help you do this by default on mobile!
