The current implementation for chat accounts (IMPP) is an input field with the type URL.

This validation is too strict and is confusing. See Thunderbird Developers Matrix chat

The vCard spec demands an URI. See IMPP.

I'm unsure how to move forward from here but my ideas are:

• Using an input field with type text (to support legacy chat protocols)
• Providing a suggestion list (datalist) for popular chat protocols
  • matrix:u/
  • irc:
  • xmpp:

See also https://phabricator.services.mozilla.com/D146313#4795612 for details on the URIs.

Seconded. I think Nicolai's proposal would provide a better UX here.

FTR, Jason's testimony from Matrix:

It took some serious banging my head against a wall to figure out Tbird wants a URL here, and then more sleuthing to figure out how to turn my Matrix username into a URL. Just wanted to point out that from my POV it's not a good experience.

Add title and rolling placeholder displaying example from various protocols.

Adds displaying chat accounts on the display page - they were missing before.

I think this patch broke some tests: https://treeherder.mozilla.org/jobs?repo=comm-central&selectedTaskRun=AqB_7QUrTRelwNZa4nDzBQ.0

Argh, will land a fix shortly.

Reopening to fix irc protocol pattern and a selection issue Martin noticed.

[Triage Comment]
Approving despite string status. The justification is that Bug 1789990 is serious enough that it needs to be fixed now, and it required the changes in this bug that were not possible without the string changes. It's noted for the record that untranslated strings in a release version make for a poor user experience. The consensus is that having a broken feature with perceived data loss is a worse experience.
As of yesterday, 6/10 tier one locales had translated the new strings with about 33% of locales overall.
