Almost?! Wow! I'll take that as a compliment. I just assumed it was completely unusable on an untested platform like that ;).

Again, very sorry for the experience, and if you'd like to get involved helping make it work great on Android for Firefox, source code is:

Or we'd gladly accept any grants to prioritize that kind of work!
