Hi all. Firefox has been my browser of choice for 15 years. However, I've noticed that it seems to be somewhat... slow and clunky. The youtube videos are all choppy for 15 seconds and the words don't match the mouth. This disappears immediately if you switch over to fullscreen. But if you go back to small screen, it's probably going to be choppy again. This may have something to do with the reason that some ads make it past Adblock Plus, on youtube. It's almost like things are loading in the wrong order... or something. I've never had this kind of trouble before, the ads have always been blocked when using Windows or Mac.
It also doesn't seem to like to load dark themes for sites right away. It usually flashes your eyes with a bright white screen first, and then loads all of the darker themes. In fact, most websites just don't load very smoothly. So I'm wondering if this is a firefox problem, and maybe I should just switch to Chromium or something like IceWeasel or Icecat or whatever it's name is these days. I know that's a firefox fork, but it could be that they do a better job with linux than Mozilla is doing these days.
Anyone else have this same kind of clunky, slow behavior out of firefox? System specs below:
