I, personally, can’t handle having more than like 6 tabs open at a time (not including pinned tabs, which I can have 1 or 2 of at a time on top of that). It gets to where I actively close tabs to try to get my tab number closer to like 2 - 4, which is usually where i’m comfortable with.
Considering my first browser was Netscape Navigator, I think it’s just that I’m stuck in the past.
Don’t worry, I’m totally stuck in the past with some things too. Certain things were just better back in the day. Even though I’m hardly old enough to really be saying that sort of thing. xD
