1669844 - Add a "Printing" section to about:support

Status: RESOLVED FIXED

(Toolkit :: General, enhancement, P1)

Description

[Jonathan Watt [:jwatt]]

Backgound: In bug 1666956 I added back the printing preferences to the "Important Modified Preferences" section since I wanted to uplift that patch to Beta, and that avoided the need for any localizable strings. Really we don't want a whole load of printer settings cluttering up the "Important Modified Preferences" section though.

I think we should have a separate Printing section in about:support that lists all the prefs beginning with "print_" and "print.", and add a "Clear saved print settings" button to assist users in recovering from print settings corruption. (To avoid duplication, even the few print prefs that we included in the "Important Modified Preferences" section prior to bug 1666956 would move to this new Printing section.)

When run in the Browser Console, the following appears to work to clear the print prefs:

XPCOMUtils.defineLazyModuleGetters(this, {
  Preferences: "resource://gre/modules/Preferences.jsm",
});
Preferences.resetBranch("print_");
Preferences.resetBranch("print.");

I missed to add this change on the last update, but the test change did
land.

Seems similar to the modified preferences so remove them for now as
well...
