In light of this recent development that's what I just switched to. I was using the 64-bit builds over at http://wiki.mozilla-x86-64.com/Firefox:Download http://wiki.mozilla-x86-64.com/Firefox:Download when Adobe first kicked out a 64-bit beta of Flash. Later I switched to the official Nightly builds when they went 64-bit. Unfortunately I'm not able to offer much insight into if it was better. Aside from a couple of short strings of bad builds that caused crashes I never had any issues with them.
