My personal test case will be with the UniFi 5.7/5.8 Controller web interface page. I've found consistently under the last few versions of Firefox that, while it's fine for at least an hour, if I leave it up constantly for ease of monitoring then after a day or two the Firefox process inevitably ends up pegging an entire core. There is no video whatsoever or any particularly fancy graphical usage, and while they may be doing something odd internally (I haven't had time to really dig into it) I'm not sure Firefox should end up in that state there over time. It's relatively easily repeatable though (will take a day but requires no interaction on my part) so I look forward to testing it. Although if it does resolve the problem I'll be mildly bummed whatever fix it was didn't make it into ESR, but so it goes.
