This is how Firefox fell behind Chrome and bled their entire market share. The strategy of letting Chrome out innovate them and then copy what they think is good is not a strategy that works.
"Does it have tabs? OK. Fine."
Firefox losing market share were probably more due to Google nagging desktop users than features.
What did Chrome have that Firefox didn't?
Basically Google exploits their market dominance in Search and Mail to get people to use Chrome (and probably their other services too). When you search in a non-Chrome browser, you'll be constantly informed by Google about how much better their search is with Chrome through pop-ups and in-page notifications (not browser notifs). If you click a link in the Gmail app on iOS, rather than opening the browser, you get a Chrome advertisement if they detect it isn't your default browser.
This goes hand-in-hand with Chrome being the default Android browser (don't underestimate the power of being the default) and Mozilla alienating their core audience of power users by forcibly inserting features that those power users despise.
Chrome never won on features, it won on marketing and abuse of a different monopoly.
