I don’t use the main YouTube website at all anymore. A big reason for this is that I spend a lot of time using a really weak laptop that tends to struggle with the JavaScript-laden abomination that is modern corporate web design. Firefox itself struggles as well, so I primarily use Luakit with Invidious, which runs peachy. I also put together a local html page for my bookmarks that is generated from Yaml using a small C application (which is not optimal, I know, but I’ve been learning C and this was a good opportunity). Whenever something doesn’t work in Luakit, I evade to Palemoon. I also tried watching YouTube via mpv earlier, and it’s great! It runs infinitely better than any web player at max resolution and buffers the whole video. Never going back.
