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.
I tab hoard to the point to where I hit my swap sometimes. Though tab hoarding is pretty common I think.
