I can't find any other reports of it, but I was on FF 47.0.1 on Windows 7 and upgraded to 48.0.1 (For some reason I never upgrade when prompted on the XX.0 releases). And I would have intermittent whole-browser freezes that lasted about a minute. Not like one every 4 hours, but more like once every 5~10 minutes. Back down to 47.0.1.
I tried again on 48.0.2, ... same thing.
I can't nail it down specifically enough to file a proper issue report, so I guess I'll keep trying when the next releases come out.
I also notice that webapps seem to like Chrome better, but FF usually performs "well enough" that I've put up with it because I find it (for me) to be markedly better at helping me deal with the ginormous amounts of text content I apparently consume. But webapps have been degraded enough for the last month-or-so that I'm running chrome in parallel just for those.
I love FF and I'm hoping that this is one of those isolated things that the fabulous team over there fixes before too long. (I suspect it's a JS related something or other, but I haven't been able to track it down specifically.)

(Wow. Now there is a rambling comment!)
