There are already other open source forks of Firefox that are community driven and maintained without employees or a for profit organization behind them. The obvious example is LibreWolf which describes itself as “a custom and independent version of Firefox, with the primary goals of privacy, security and user freedom”. There’s no argument that maintaining a web browser is currently complex and needs to make security first decisions, but LibreWolf as an example shows us that it is not only possible but I argue proves it will continue even if Firefox as we know it goes away.
I’m a Librewolf fan too, but the majority of the hard work is done by Mozilla developers. Their work is very important too, but what they are doing is preconfiguring prefs, adding patches, and writing the patches sometimes. Much easier to be done as a team of volunteers.
Those forks aren’t maintaining Firefox itself, just their own modifications. If a bug is found in Firefox, the LibreWolf team don’t have to fix it themselves, they can wait for Mozilla to do it, and incorporate the fix once it materialises. There are forks that diverge further, but they either get quickly abandoned after their creator realises how much of a headache maintenance will be, or they’re left with gaping security holes.
