From where I sit, it looks like there has been a lot of technical effort going into Firefox in the last few years - like 'Electrolyis' and 'Quantum'. 'Quantum' in particular has been translating the more experimental work (Rust & Servo) into improvements in Firefox. So it seems more like they've been losing marketshare despite investing in Firefox. Google has much more money to spend on development, and can potentially also make popular sites like Youtube or GMail work best in Chrome. I use Firefox and I hope it will get more popular again. But I'm baffled how many people seem to think that if only Mozilla tried properly, the users would come flocking back. All the evidence suggests that most users go to Chrome no matter what they do.
