MacOS — Per-profile Dock icons that launch the correct profile (even when Firefox is closed)

[Max1m]

## Request Summary

On MacOS, let each Firefox profile have its own Dock icon. Clicking a profile's icon should open Firefox directly into that profile — including when Firefox isn't running — with no Profile Manager prompt and no picker.

## Current behavior

All profiles share a single Dock icon. There's no way to pin a specific profile to the Dock or tell profiles apart there. Opening a given profile requires `about:profiles`, the Profile Manager, or a manual command line — none of which leave a persistent, clickable Dock icon.

## Expected behavior

• From profile management (e.g. `about:profiles` or the profile menu), the user can add a profile to the Dock.
• Each added profile gets its own distinct, pinnable Dock icon.
• Clicking a profile's Dock icon opens Firefox into that exact profile:
  • if Firefox is closed → it cold-starts straight into that profile;
  • if that profile is already open → its existing windows come to the front instead of a duplicate opening;
  • if other profiles are open → a window for this profile opens alongside.
• The user can give each profile a distinct icon or color so the Dock tiles are easy to tell apart.
• Renaming or deleting a profile updates or removes its Dock icon accordingly (no orphaned icons).
• Users who don't opt in keep today's single-icon behavior unchanged.

## Why

Many people separate work, personal, client, or development browsing into profiles. A per-profile Dock icon makes switching a single click, always lands in the right profile, and matches what macOS users expect from the Dock. This is consistently requested and currently only achievable through fragile third-party scripts.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

Yes please! When I have different profiles open, I can click "Keep in Dock" for a profile-specific instance but it doesn't actually persist. When closing Firefox and trying to re-open from that profile-specific icon, it doesn't boot at all. The only way it currently works is to open a main Firefox instance and then manually go to Profiles and select a another profile, which then opens a new Firefox window with that profile.

The current behavior is starting to become annoying, because every Firefox update requires me to close all Firefox windows and I have to manually open additional profiles after the update, as described above.

yes please, its crazy that this isn't the default

Yes please, the only workaround would be to install multiple versions of Firefox, two install instances of the same or one would be Firefox ESR, or Developer edition, then we could have one icon per profile (ideally a different icon but that's another story), but this is overkill just to use profiles on MacOS the way they were intended to.
On Linux, it's easy to just create 2 desktop files, configure profiles and icons. It should be available in MacOS.

Yes please!!

It is extremely annoying that when I open a new Firefox window which is not using the profile I want, that I need to open a new window in the correct profile from there, and then close the empty new one in the wrong profile.  

Some other related improvements I would like to add:

1. When you are in an empty FireFox window (no website opened) and you open a new profile, close the current window automatically and open the new one.
2. Add a right-click option to the Dock icon which offers "New Window" with the different profiles available (Just like in Safari).
