Been using revanced, sometimes using Iceraven (ff fork) w/ ublock origin on phone, and using librewolf (another ff fork) also w/ ublock origin on desktop. So far never encountered slow down since November 2023.

Is this slow down only on select extension issue? Although when it first happend (late 2023) I was thrown up by sudden yt not loading on my librewolf but it only happend only on single day, afterward it gone.
