Firefox is very dear to me. I use it on my computer all the time for how much more relatively secure it is from other browsers. But Android version is a hellish nightmare. When I open the app, even with no previous tabs on, it will not be responsive for more than 30-45 seconds for seemingly no reason. Same thing when I kill the app and start it again. If it does have open tabs, it will either not be able to fetch their sum number to be displayed on the top right corner until that aforementioned timespan passes, and/or I wont be able to remove/add tabs until again that period of time passes! This is a blocking issue that's been there for well over a year and a half, if not longer!
