Is anyone else having problems with Firefox on FC39 with XFCE recently? After rock solid operation for a long time, in the last 2 or 3 weeks the UI has been fouling up every day or two when I do some seemingly mundane operation in Firefox. A couple of times Firefox has crashed after a few seconds. The foul ups sometimes only affect the Firefox windows, and other windows still work OK. Sometimes the whole desktop fouls up, and I have to switch to a text only screen and kill Firefox. That restores normal desktop operation for all the other windows.
