Lately, when I load FF, I get an instantaneous flash of a white screen, then FF will open.
Today, twice when I tried to open FF, it opened only to that white page with a message saying that FireFox was not responding.
I ran CCleaner then opened and closed Edge a couple of times and finally got FF to open again, but I still get that instantaneous flash of a white screen before FF loads.
What can be causing this and is there anything I need to do?
