Extensions are still limited in countless little ways many months after the Quantum release. Every one of them makes the browser a bit worse than it was before. The claims about making extensions safer and more reliable have proven to be optimistic, with a string of problems around both instability and privacy since the big change.
More generally, I come across sites that don't work properly with Firefox several times a week these days. Chrome is the new "This site displays best at 800x600 in Netscape Navigator" and Firefox's market share has fallen so low that a lot of web developers simply don't test with it properly any more. Maybe this isn't Mozilla's fault, but realistically it is still their problem.
As for speed, while some people seem to find Quantum a big improvement in speed, it hasn't made Firefox noticeably faster than other major browsers for most day-to-day use.
I want to like Firefox. It was my primary browser for years, thanks to a combination of flexibility through add-ons, being relatively good for privacy and security, and having relatively good developer tools (all of these being somewhat related). But as someone who uses all the major browsers professionally, I can only assume that the leadership at Mozilla have chosen a strategy of trying to out-Chrome Chrome, and that is going about as well as anyone more objective might expect while still giving up almost everything that was a natural strength for Firefox before.
