Tab list usability remains pretty much the same regardless of how many tabs are open.

Also, if you're wondering why my tabs look like they're from 2017, that's just another benefit of using Firefox [1]. Although as nice as it being able to actually customize our browsers, it would be nice for Mozilla to stop breaking things for sake of breaking things.
Thanks.
