That's a bit harsh. Every point they raised is valid: the UX changes have been weird and inconsistent, the lack of history searching is frustrating etc I still use ff, I certainly won't be using Chrome as I appreciate my add-ons too much.

If Firefox on Android is a "mess", what does that make Microsoft Edge? :- )
