Firing their entire servo team using Rust and then most of their docs team (MDN) and then giving the CEO a raise was the beginning.
Now their tech sucks and market share is sinking.
I don’t think it’s the only reason, but firing Eich didn’t help. Also, Brave has been a pretty nice browser with lots of small quality of life innovations. It’s a shock to me that Firefox didn’t capitalize on its unique position to be privacy focused.
