Earlier quoted context omitted.
I'm old and I code for a living, I have maybe at most a dozen tabs open on any day. I can't imagine needing 80 but now I see why chrome has that new search tabs drop down.
On my main Firefox profile I'm rarely below 1000 tabs. I also use them as bookmarks and backlog, and every couple of months I scroll through the entire tab bar and close everything unimportant. The address bar also searches all open tabs and lets me jump to matches.
What do you lose from closing tabs versus what do you gain from keeping them open? For me, if I use a site open it’s bookmarked or already in history so it’s fast to reopen. Closing tabs keeps my machine fast and memory usage low and also makes me faster at switching between the open tabs as I don’t need to search or parse through many UI bits.
