That’s totally fair, too. Not everyone gets bothered by the same things.
The last set up I used was this one and what made me give up is that it is so easy to accidentally close it. I had to look through my Firefox history to find that and when I closed the history sidebar, my tab bar was gone. It’s just a press of F1 to get it open, but why can’t I just make it persistent? Why does it have to share the same space as so many other features in Firefox? I don’t care if history wants to occupy the same space for the moment I need it, but when I’m done, go back to showing my tabs.
