Firefox dropped below the 10% share value on Netmarketshare

At least back in the mid 2000s if you ever saw banners that said a site needed Firefox to run properly it was because people were on IE which didn't support new standard HTML features. Not because devs didn't test their JS outside of Chrome. If you can't code for more than one browser you shouldn't be a web developer imho. Unless you're doing Electron or something.
People who actually write websites people use and thusly they support everything from IE11 and up.
Or the ones that shit out the latest trend in webdev which only supports the Chrome version the author used.
Firefox will never match Chrome head-to-head, and is a dying browser. Then only way Chrome doesn't win is if a new competitor appears.
I switched back to Firefox around version 57, and the only 'performance issue' was initially having to re-learn stuff that was muscle memory in Chrome. Once I got up to speed the user experience is indistinguishable from Chrome - even on the crappy old netbook I sometimes have to use.
The thing that might kill firefox is the aforementioned shitty web devs with their bogus UA checks, Firefox having a history of bad performance/stability, and most people already using Chrome with no reason to consider switching.
In an ideal world we'd have about 25% to Edge, 25% to Safari, 25% to Firefox and 25% to Chrome.
I tried to switch to FF completely - for dev work and all - late last year. The dev tools were just not as good as Chrome/Chromium. I use FF for browsing. I'll try to make the dev switch again, starting today.
I use Firefox Developer Edition for dev work. I prefer Fx's tools, and it's a walled garden where I don't have any other plugins that could possibly interfere with anything I'm doing.
Excessive JS usage is probably the culprit behind the move to Chrome. A number of popular sites are so packed with JS that using Chrome is the only way for normal users to achieve reasonable performance.
If the page actually does anything on top of that the problem grows quickly.
Are we really saying that Chrome is just more efficient at wasting CPU cycles to show adverts?
