I prefer using the FireFox browser on YouTube, but several months ago, it began developing a problem. Videos halt and then the rotating circle appears and keeps turning and nothing happens. If I skip past it, it restarts and runs for a few minutes, but then stops again. The machine is W-10, FF ver. 115.6.0esr (64-bit) but it can also be configured to run W-7 and it does it there too. A number of longer, higher quality videos (8kEarth, 8kParadise) don't seem to have the problem and it only does it on YT. All the videos run correctly with Chrome. I've refreshed FF, but it hasn't helped. I also disabled hardware acceleration. Anyone else had a problem with this?
