We are no longer blocking this pref flip on bug 1931299 because that bug turned out to have deeper platform-level complications than anticipated.

:jhirsch do you want to nominate this for a release note? (Process info)
We could include it in the nightly only release notes, if you want visibility for nightly users

Here's my draft -- please feel free to amend so it's appropriate (this is my very first one of these, here at Mozilla, and I'm still learning our tone, etc.)
Release Note: Nightly ONLY (136)
Category: New
Description: So users can more easily create and switch between profiles, profile management for Firefox desktop is now on by default in Nightly and under active development.

Thanks, added to the Fx136 nightly release notes, please allow 30 minutes for the site to update.

Verified as fixed using Nightly 136.0a1 (Build ID: 20250117095907) and the latest Nightly 137.0a1 – the preference that enables Profile Switching ("browser.profiles.enabled" = true in about:config) is now enabled by default in Nightly - tested on macOS 15 and Windows 11.

Removing from Nightly release notes since this is rolling out in Fx138
