I would trade all these things, in a heartbeat, for the ability to keep other tabs/windows working when one tab is in a hard loop. That one facility is the thing that means I can't let go of Chrome, even though Firefox is prefereable in so many other way.

That was exactly my issue with Firefox. They mostly fixed it in 2016 [1], though I still found a few issues. These days, it seems mostly to be a thing of the past.
