You'll be waiting for a long time. Nobody can "fix" this, except Adobe. 
They've been flapping their gums about releasing a 64 bit Flash plugin for 
many years. I do not expect to ever see a 64 bit Flash plugin.

However, nothing stops you from installing 32 bit Firefox, which will run 
just fine on a 64 bit Fedora install.
