FF has tab containers which, while I haven’t used much myself, seem pretty similar to tab groups from a quick search.
Edit: Also looks like there’s “Simple tab groups” extension which maybe even more similar to what you may want
I know I would just like if it was a bit more lenient, I have an older phone and an otter box on it so getting it to register the exact edge is quite difficult for me sometimes.
It’s a screen door, mainly for the purpose of being able to open your front door, but not let bugs in. (Or the cats out)
