I'm back to using v7.8 currently, as v8.x seems to be more trouble than it's worth using, or actually sitting and waiting while nothing happens for most of the time, with either the CPU running at full speed while the page and the whole browser is "frozen in time"!

There ought to be some way to interrupt any webpage/JavaScript (tab) and either pause or halt/kill it whenever it causes more trouble than it offers the experience it is supposed to. I can't even get Task Manager to launch to send a "Break" to Wayfarer to stop it (wasting CPU cycles doing nothing) as the JavaScript has a stranglehold on the system, which should just not be possible.
