I am not toooooooo sure; I’m not familiar with lemmy myself. You could try adding the scheme before it, so: https://lemmy.world/c/beebutts or perhaps go about it the long way with url linking [lemmy.world/c/beebutts](https://lemmy.world/c/beebutts)

Firefox runs really poorly for twitch and youtube videos for me in linux; mainly in CPU. Brave will use maybe 10-20% of my cpu for a single twitch stream whereas firefox uses about 80%. I use firefox for all my browsing, but for videos it just doesn’t seem to work well… Perhaps a different chromium browser would be better as you say.
