3 stars: I want to move away from Chrome so Firefox felt like the next best option. Duckduckgo is nice too but I don't like the UI. I have complaints though: switching between tabs, refreshing the page among others should be a 1 step process: not having to go into the hamburger menu to do so. Look at what Chrome does well for its users and incorporate those/similar features. If you want to beat the competition.

4 stars: Although all [Web] browsers throughout the years have tended to get clunky as they've matured -- contrary to the idea that codebases become refined over time -- this one is still half-decent.
3 stars: Just let us be able to access about:config again, having to hit enable desktop every site/tab/link is tedious. I'll come back if about:config is reinstated. Until then I have to use a different browser so I can browse as desktop permanently.
3 stars: You are handicapping us: 1. Pl Improve FF SYNCH: cannot synch collections, defeats the purpose of easy access, across devices, to tagged sites. I thought that would be an obvious given expectation. 2. Please put back save as pdf. Per above, I switched to collections as a workaround to not having save as pdf. But THAT does not across devices.
5 stars: love Firefox, it seems to allow me to do stuff that I can't in other browsers. Wish there were a few more plugins available for the mobile client.
