Running bullseye in 8GB (½GB swap is unused), FF has 124 tabs listed. However, only about a dozen are active (as listed by ps and topmem). So that's really the statistic to report. All the rest of the tabs have yet to be visited since FF was started. I restart FF every morning, and it restores all the tabs from the previous session. Now, were I to Ctrl-PageUp my way across all 124 tabs, the machine would grind to snail's pace of swapping. So I don't. The tabs are localised: there are clumps related to different problems, so stuff I last looked at, say, a fortnight ago will be many tabs to the left of where I'm working now. I use the ▽ at the top-right to navigate around, so as to skip over intervening tabs without waking them from their dormant state. Every few months maybe, I have a killing spree, killing off many clumps, though the BBC schedules at the extreme left, for example, have been there for years. I've also run a second FF today, as a different user, just to download a couple of bank statements. That browser will never usually have more than two or three tabs, all on one site, and I close them all before I quit that FF. That said, I've not noticed any slowdown recently. The first instance is not quick starting up, but that one generally has to compete with the daily housekeeping that occurs after I boot up. Subsequent instances are quick. Cheers, David.
