We're going here

And read about brand new and consistent rules for markup generation within contenteditable divs in modern browrsers:

"Fortunately, in modern browsers things are somewhat more consistent. As of Firefox 55, Firefox has been updated to wrap the separate lines in <div> elements, matching the behavior of Chrome, modern Opera, Edge, and Safari."

But lets try the form on that exact page? Lets enter some data, than hit Enter, than more data, Enter once again, etc.

Actual results:

<div contenteditable="true">
  This text can be edited by the user.

Expected results:

<div contenteditable="true">
  This text can be edited by the user.

Hi mega.venik,

I was able to reproduce the issue you are experiencing on the latest Firefox Release (57.0.4) and on Firefox Beta 58.0b15 but not on Firefox Beta 59.0b1 and Nightly 59.0a1.

It seems that this feature is behind a pref (Bug 1354060, "editor.use_div_for_default_newlines") and it's been set up in such a way that it's turned off if you are in Release or in late Beta and turned on in early Beta or Nightly.

:masayuki, could you please confirm if this is indeed the desired behavior?

Yes. The best way of web apps about avoiding this compatibility issue is, calling |document.execCommand("defaultParagraphSeparator", false, "p");| or |document.execCommand("defaultParagraphSeparator", false, "div");| makes all browsers (except IE and Safari) use same default paragraph separator.

Ideally, we can enable it on 60 or 61 because even if we change the default settings now, Editor staff don't have much time to investigate new web compat reports.

Component: Untriaged → Editor
Product: Firefox → Core
Priority: -- → P3
Firefox 60 is the next ESR version. And we have only one regression from Nightly testers, that is bug 1406726.

So, we should fix bug 1406726 first, though, we should enable the standardized defaultParagraphSeparator in the release channel too.
