Firefox update to 91.3.0esr (64-bit) now keeps on lowering Youtube res to 360p.

<< < (3/3)

Once installed, I can no longer read EEVBlog when scrolling the screen.  The display refresh jumps similar to my old 50MHz Amiga in a text editor even though EEVBlog is like 99% text.  It's like going from 60fps to ~12fps.

It does seem to use 100-200mb memory but I don't see the CPU problem, maybe turn off all the overlay controls?
How much memory do you have?

If you have any kind of ad blocker that may be the reason. I have both AdBlock+ and the "Enhancer for YouTube" extension, and I never get any commercial in YT videos. I haven't noticed it had an impact on resolution though. At least in my case, resolution dropping is usually the consequence of my internet connection getting slower throughput. Some ISPs also do some kind of automatic throttling based on time of day and IPs - in particular for streaming web services - to avoid saturation.

Cheating? ::)

Anyway, I've never noticed any issue whatsoever with it here. It may eat up that much memory but frankly I can hardly notice - Firefox already gobbles up GBytes of memory when used with many tabs open, so... (not saying this is good but just how it is and my machines have from 16 GB to 64 GB of RAM.)
