I switched a few months ago and am pretty happy, once you find the right addons. The reason I switched was some niggling privacy concerns and then discovering that google-chrome won't allow Ghostery to block doubleclick. Firefox with: adblock-plus, ghostery, noscript, requestpolicy, refcontrol and cookiemonster addresses all the privacy concerns. Then: add to searchbar, customizable shortcuts, duplicate in tab context menu, firegestures, open link in ..., and sessionmanager give me pretty much the same UX as I had in google-chrome.
