Yeah I don’t really get it but it seems like it’s not that uncommon to have heaps of tabs open. More than 7,000 is obviously exceptional but it checks out - there’s a few users like this in mozilla’s telemetry.

I think it’s basically just concern that you might not be able to find your way back to something you were looking at before. To me that seems irrational but everyone needs to sail their own ship I guess.
