Firefox is finally getting flash support. Support for the plugin landed in the nightly builds a few days ago - meaning you can try it yourself, right now.
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.
