1697506 - [Proton] Update dialog styling for content handling application chooser per new spec

Status: NEW

(Firefox :: File Handling, enhancement, P3)

Description

[:Gijs (he/him)]

See https://www.figma.com/file/FjUe6ORvXZgJvI3rPuTV33/Desktop-UI-(Mozilla-Confidential-)?node-id=5%3A2 ("Firefox Modals" section in the figma spec, column "spec 2 / "External protocol handler")

Code is in https://searchfox.org/mozilla-central/source/toolkit/mozapps/handling/content/appChooser.xhtml .

• selected item in the richlistbox should not have a different background, but get a checkmark instead
• up to 3 items should be reliably visible in the richlistbox without a scrollbar (keep in mind that we can't make assumptions about font size and thus individual item height; we'll need to use em or similar to size the box). If there are fewer items, the box should be less tall.
• stop showing "choose application" as a row in the list, but show as a separate button instead ("Choose other application...", use the .small button class)
• show only the domain/hostname for the handler, and show it on the same line as the name (but with a smaller font size / different foreground colour)

Clearing p2a whiteboard given this got marked P3.

Doug, are you actively working on this?

Ack, sorry, no. I can still take this if extra hands are needed and it's any priority, though.
