I _want_ to use Firefox, and Mozilla's kit but every single time I've come onboard after watching improvements etc I get shafted by updates which change major things every few weeks, this is mostly around Firefox having constantly had a different URL bar every update and them removing the ability to search for preferences in my preference list. It feels like they are fighting my ability to make Firefox exactly how I want it and that results in me going to a better take-it-how-you-get-it browser: Chromium. It's a shame but I don't see it being any better the next time I inevitably try.
