I lost faith in this company, Mozilla has been distracted by chasing hypes, taking money from a major competitor, dropped servo development, the list goes on and on. I had to kagi for "Mozilla Foundation" NPO to confirm that it's still a nonprofit.
In today's view, I'm looking at a Ad Company depends on Google happens to own a browser. This contradicts one of it's main sale point: diversifying the browser market. For me what's left for Firefox is just uB0 support.
There's no remorse in switching to and strongly soliciting Firefox forks like LibreWolf or Waterfox.
