Firefox Unbuntu 11.10 64 bit

[gerry]

Can anyone let me know what is happening.
Each time I start Firefox in Ubuntu 11.10 it will at some point freeze.
I can recreate the problem easily by trying to run a flash video from
You Tube or any embedded video. My version of Firefox is the latest from
the updates. Now chrome is giving me the same problem :-( 

Looks like Flash is the culprit but no one seems to know the answer 

By the way Mint 11 32bit is fine 

Any pointers would be useful
