If you want to experience the magic of flash on Firefox, you can try out the latest trunk build right here (pick the .apk file). A word of warning though, it crashes. A lot.
It really works!
Luckily they've got tons of time to work the bugs out. According to the bugzilla filing, it's not going to be ready until Firefox Ten. If the desktop version is any indication, that'll be launching around January 31, 2012. By then we'll all be using Chrome 25 and flying around in spaceships.
Ok, that may have been a bit of an exaggeration, but really? 2012? Step on it, will ya fellas?
