Over the weekend, I had trouble with Firefox and Chrome in that opening the Editor to try to reply to a post caused a runaway script. Eventually you are asked if you want to stop the script (or wait it out); for both Firefox and Chrome, if you said "stop", then when you hit the Post button, nothing got posted.
I was forced to use Microsoft Edge, because while it also reported on the runaway script, when I stopped it, it allowed me to post my answer. Very frustrating, but it appears that they have fixed it now (I am doing this reply from Firefox, which would not have worked this last weekend).
