I was on holiday and out of the loop on how big of change this Phoenix upgrade would be, got a notification on Android to update firefox and went through without realizing the massive UX and functionality downgrade this Firefox version is.

Apart from the non-starter of missing add-ons, the whole UX overhaul is insane, so many things that use to be frequent single tap are now two, three, tabs plus swipe up/down business.

With the risk of not sounding constructive, I don't know who in their right mind proposed this but it's crazy to me that it went through hundreds of beta-testers without nobody complaining, or that nobody accepted feedback against this if it existed.
