1927567 - When a new profile is first created, select and apply a random theme at first run

Status: VERIFIED FIXED

(Toolkit :: Startup and Profile System, enhancement)

Description

[Jared Hirsch [:jhirsch] (he/him) (Needinfo please)]

At first run, make sure that a random theme is applied to the new profile, so users can clearly see that it's a window belonging to a different instance of Firefox.

Note there may be perceived performance challenges here related to downloading and installing the theme quickly enough to prevent an initial flash of unstyled browser chrome. We will handle this, if it is a problem, in a followup bug.

Verified as fixed on the latest Nightly 137.0a1 and on Firefox 135.0.1 (having browser.profiles.enabled set to true) on macOS 15 and Windows 11 - a random theme is applied to the profile at the first run.
