The writing was on the wall when they decided a rapid release schedule was somehow better software. Browsers are things that should grow very slowly, like oak trees.
The lack of urgency and awareness around this baffles me. The death of Firefox means the death of the open web, but it seems like very few people care.
I remember when Firefox was going to change the world. It kind of did. Today, it's clear that Mozilla wants to do anything else than build a web browser. Maybe if they did, Firefox wouldn't have the market share of an also-ran.
