Enhancement Request: Add Firefox with uBlock Origin in Desktop private modes

[Anutrix]

Any user concern with Privacy that installs Firefox does install uBlock Origin which is now no longer supported by most Chromium browsers.

Since, Brave gets a Tor mode column which is technically not a default option(an ordinary user won't know what TOR mode means and will likely stick to private mode which is self-explanatory), maybe we can it as similar exception.
