Firefox showed a message that it needed to restart to update. It did not update at restart, and the message was still there. I attempted restarts several time, including restarting my PC.
At the same time, I could not log in to Firefox to provide this message. (I had another application that would not work, but do not know if the two problems are related.)
Finally, I started the Troubleshoot Mode, got logged in, and the restart message went away, I assume Firefox updated. And now, I am able to type this message.
What has been the problem?
