Firefox keeps making blunders that are killing it.
Mozilla's lameness is really the result of privilege and possibly a lack of incentives. When execs get 10m/yr for writing blogs about sexual socialism and BLM, why innovate?
Why would FF be going our of your way, but not Chrome? Neither is the default on Windows.
And Firefox UI is going through a redesign (Proton).
