After seeing so many problems with ver 89 reported here, and with my own font display problems, I still forgot to remind my wife not to update firefox on her pc. So, she updated, started using, then firefox crashed. After killing task, firefox loaded up on a white blank window. Troubleshoot mode or whatever also gives a blank, even after restarting windows. Uninstalled 89, downloaded ver 88 and installed. Had to say goodbye to her bookmarks, saved login etc. To my horror, when I went into options to disable auto update, it was already downloading 89! Even after changing it and exiting firefox, it still updated to 89! Uninstalled 89 and reinstalled 88 again. Disconnected internet before running firefox so that I could change the update setting first. What a hassle. Can someone with powers here tell firefox devs to not beat the purpose of reverting to previous versions... Been a loyal Firefox user since the time of Netscape... Really sad to see another very problematic version... Hope the mvp volunteers and top contributors here can compile our issues and submit to the devs...
