> box would start sounding like a jet engine.

Not sure about the container connection, but Firefox also now has 'about:performance' which is pretty much like 'top for browser tabs'. When things start getting bogged down I can now find the culprit and nuke it.

about:memory is also useful, it allows you to force garbage collection on the browser as a whole.

That’s super interesting.

Was not aware of those. My observations were mostly noted while trying to figure out why one specific browser wouldn’t simply not sync any custom containers. And then I noticed my fans spin up on my macmini. I only used system monitors at the time before just disabling the add-on.

I’ll definately look at those in the future. Didn’t even know they existed.

about:performance is a little limited, especially if you have a single window, because switching to it makes it the foreground tab and all the other tabs background tabs. Background tabs can be throttled, and generally behave very differently.

(There's an experimental sidebar extension that works better and gives a graphical history, but I'm pretty sure it's unfinished and unavailable for general use. Hopefully it'll come out sometime.)
