Video and WebGL (Google Maps Street View/GeoGuesser) are a slideshow under Firefox on Linux, because they do compositing in software on Linux (copying the video buffer back and forth between GPU and RAM). That's the whole reason why I use a chromium based browser. Really missing containers. They are really letting Linux support slide. :(
Not my experience, even in a budget notebook, at least for video. I'm making sure that the video is decoded in hardware. It's a bit easier and more secure on wayland.
I'm still on a NVIDIA GeForce GTX 760, but I have a 4k monitor (X11, desktop). Perfectly smooth in Chromium browsers, but YouTube and Street View are basically unusable in Firefox. Before when I had a Full HD monitor it was usable in Firefox, though even back then Chromium based browsers where a bit smoother at those tasks. And yes, I've set all the flags in about:config that you can find on that issue. No change.
But I need to upgrade my PC. When I do I'll try Firefox again. Would be awesome if it would work for me again.
