LibreWolf (Firefox-Based Browser)

There was some work to support the MAR updates a few years back, but I am not sure why it was never finished. My guess is that, since we already had the bundled Windows updater (which was supposed to be a temporary solution), it wasn’t seen as a priority. I looked at how Mullvad/Tor Browser handles MAR updates a few days ago, and it should be doable and is something that I have planned on supporting.
