Go into settings go to the general section and find the browsing heading uncheck the box next to Use automatic paragraph spacing.

That option doesn't seem to be there - see attached pic.

Were you previously using editor.use_div_for_default_newlines = false to get a <br> ? Support for editor.use_div_for_default_newlines and several other editor prefs has been removed in 112 (bug 1815827) and now defaults to <div>.

You can use Shift+Enter to get a <br> tag.

I am completely clueless about using editor. Are you suggesting I have to use Shift+Enter for a simple return at the end of a paragraph? Major PITA!!!!

Terry, I followed your link and here's what I see: (see below).

Like I posted above, editor.use_div_for_default_newlines is no longer supported in 113 as you can see by the trashcan icon at the far right. You can click the trashcan to reset/remove this pref. If you press the Enter key in a rich text editor then you create a new DIV element that is rendered as a extra return. You need to use Shift+Enter to add a linefeed (simple line break) in the current DIV container.

Thanks for the info - even though it sucks. Why would "they" do this? I know, not your job, but it makes no sense to me.

So, is there any other work around for this? My feeble mind is incapable of remembering to use shift+return some places and not in others. Am I the only person in the world having this issue?

It is theoretically possible for an add-on or script to intercept the Enter key and modify what it does in a page. I don't know whether there are any add-ons or userscripts for this out there in the wild, or whether a new one would be needed.
