I am curious if you how how this compares to The Great Suspender? I also don't understand why Chrome and Firefox don't buil tab managers directly into the browser.
Firefox used to have Tab Groups, it got removed but the webextension API got some new features specifically to support similar functionality in an extension.
Thanks. Yeah I suspect tab junkies are probably a minority. Do you know is the latest Firefox on par with Chrome in terms of tab usage and memory footprint?
Memory usage in FF with lots of tabs seems a bit better than Chrome, CPU usage seems a bit worse. I think the UI does a significantly better job of handling them though, since Chrome just shrinks everything until there's no text left.
About a year ago FF was really awful with lots of tabs, CPU usage was very high and the UI would occasionally freeze up for 10+ seconds at a time. They're really been making some big performance improvements lately.

In reality I think it's just not a priority for browser devs because the overwhelming majority of users do not use huge numbers of tabs.
