First Enter key in text box erases text above
I have observed this bug only in Disqus, but another Disqus user has seen it in other web sites viewed via Firefox, so maybe you could check your logic. Here is the original bug:
When entering a Disqus comment [or possibly other text boxes] and using the Enter key to end the first paragraph, the text typed so far is erased. It can be recovered by immediately pressing Ctrl+Z (Undo), but this is not obvious; most users will think they just lost that text, and will retype it. This was sporadic for a year or two, but right now (morning of 10/2/2023) it seems to happen on every comment I type. In the past, it only occurred on the FIRST Enter key, at least if I recovered via Undo. The only contact I have with Disqus is in the comments on an episode of the Kevin and Kell webcomic (https://kevinandkell.com). I am running Windows 10 on a Bootcamp'ed Mac, and my browser is the latest version of Mozilla Firefox.
Disqus user FreedomFighter replied:
That is a common problem unique to Firefox. When you hit enter and the post erases, right click in the box and click on "Undo" to get the text back, then you can do what you need to do whether is type more words, or post the comment.
[His recovery is essentially the same as mine, only using the mouse rather than the keyboard.]
Could this be an interaction between Firefox and Disqus? I have not personally seen this on any other website via Firefox, but FreedomFighter apparently has seen it elsewhere.

I can't reproduce this. Does it still happen in Troubleshoot Mode?

It didn't with the first test, but the problem is sporadic anyway. I haven't noted any specific factor that forces it to happen (such as size of paragraph, last character before Enter, etc.). The day I filed the report, it was happening consistently for about five of my comments respectively on one thread, and others were talking about the same bug, saying it was consistent for them also. I gave my workaround, which probably helped some. Then I went to the next day's episode and followed the comment stream on that one, and the problem went away. I have never seen this on any other web site but https://kevinandkell.com, whose comment stream is managed by Disqus, and I have not used Disqus in any other environment except that one, but another user mentioned it as a Firefox problem, but did not mention where, other than Kevin and Kell, they encountered it.
So, both Mozilla and Disqus are aware of the problem, as is the moderator of K&K (Bill Holbrook, who also draws K&K and other webcomics) if he has been monitoring his comments. Nothing can be done to diagnose the problem with certainty, so I guess we'll have to close the active report, but be looking out for the symptom in the future. If I see it on any other web site, I'll file a new report and reference this one. Thanks for the help.
