Yes Firefox supports flash player content.

Read help on this page: [[Install the Flash plugin to view videos, animations and games|https://support.mozilla.org/en-US/kb/install-flash-plugin-view-videos-animations-games]]

That article above is for PC, the user is using android, and yes Firefox does use android flash.

im sorry forgot to mention my question is for android.

Waka_Flocka_Flame, your answer is both right and wrong.

While you can technically still run Flash on Android manually, Google Play has not provided Flash for Android 4.1 and newer and Adobe has stopped supporting Android as of 4.0 so the Flash plugin is potentially rather insecure now.

Flash Player 11.1 for Android 4.0 (11.1.115.63)

Also what is your phone or tablet as because if it has a Tegra 1 or 2 cpu and maybe 3 or newer, then Flash may be crash prone.

I have a droid RAZR Jelly Bean 4.1.2 i use flash player 11.1 and it works fine with the stock browser but its slow, fire fox is faster. But flash. Player isnt working along side with F.F. so im hoping theres a plug in.

James, I wouldn't know that well, sorry about that. I don't use android a lot.
