User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:55.0) Gecko/20100101 Firefox/55.0 Build ID: 20170721185346 Steps to reproduce: In firefox 55 and 56, all tabs become blank when I alt-f2 ->r in Gnome-shell. This bug does not happen in firefox 54. I'm not using wayland. On the same desktop stack, firefox 54 and 52 do not show this issue. To reproduce: 1) install firefox 55 or above on gnome and open a few tabs. 2) press alt-f2 to bring up the run (enter a command) dialog. 3) type r and press enter. Actual results: gnome-shell is reexecuted (same PID). firefox tabs are now blank. firefox main process memory usage also dropped by ~30MB. I am using NVIDIA graphics. Just to be clear, downgrading to firefox 54 or 52 'fixes' the issue.
