There's some speed penalty. Native 64 bit application benefit from having more 64 bit registers on the CPU.

Define "stable". If "does a 64 bit kernel crash more often than a 32 bit kernel", the answer is no. 64 bit is on the parity with 32 bit when it comes to general stability.

Now, when it comes to non-free binary blob device drivers, the availability of non-free binary blobs is somewhat better for 32 bit than for 64 bit. To my knowledge, there is no 64 bit version of a browser Flash plugin.

If you do not need Flash, and you do not use non-free binary blob device drivers, 64 bit will work just as well as 32 bit.

Ok that's the problem, I want flash, I wait and see if someone fix that.

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.
