I have loved, and used (exclusively) Firefox on both mobile and desktop platforms for many years. But they killed all the best parts, so I downloaded and installed an older version that had what I wanted. Only downside is that I have to manually update all my other apps so that Firefox doesn't overwrite my install. A pain, but well worth it! Well, per developer advice I checked back in. Still not worth it. I will continue to use the desktop version, but without the add-on support, it's trash.
