So on my macbook when I enable fullscreen the anmation is super weird. first it stretches the video to the top and then just expands to the whole screen, when I go out of fullscreen is stretches to the bottom and then goes out off fullscreen. for example on safari it just expands the video until it takes up the whole screen. I have gone in about:config and disabled the fullscreen animation but that did nothing.

Hello, I want to get funky looking tabs like this:

But I can't figure out how to do it. I've tried searching for a way to do this, but everything I find is very old and doesn't work. One thing I keep finding is this: https://github.com/wilfredwee/photon-australis

But that doesn't work for me, it just makes the tabs less tall. I've tried switching to nightly and that didn't do anything so I'm pretty lost. I don't know CSS or anything so I cant do it myself.

If anyone knows how to do this then please tell me!! thx!
