Lately, Firefox + uBlock Origin and YouTube on Linux is sometimes horribly slow for me. It uses all the CPU and chokes my computers. Sometimes it’s even difficult to just seek in the video, as it’s so sluggish.
It seems to vary depending on the type of ads. It’s not “random” because a video that has this behavior will always do it, even if I restart FF, while others will be fine.
I thought it was my old computer at first, or that I was out of memory, but the same thing happens on my modern Ryzen.
Although I notice it less and less, so maybe it was a bug with YT + uBlock.
And it’s only on my Linux computers. On Android, FF + uBlock works super well.
I’m now wary of crocs since I sprained my ankle while wearing them.
