Unity 3D Keep Crashing in every site!

Hey guys! I try everything to make the unity 3d webplugin works!

Already deleted from my: /Library/Internet Plug-Ins reinstall a bunch times! Try in Safari, Firefox, Chrome and Chrome Beta, reinstall with all browsers closed, reinstall with all browsers opened! Just keep Crashing!

In the Safari - just crash and i must close the browser with Command+ALT+ESC In the Firefox - Just the bootcamp here works some times: http://unity3d.com/gallery/live-demos/index.html#bootcamp, but if i enter in the link now, i just get sound, and noting is show at page! And i must close the Browser forced too.

In Google Chrome normal, just keep crashing in every browser In Chrome Beta, the unity page tell me i already have Unity3D installed, but no one unity 3d Application! I can even check what version of unity i have anymore!

Anybody know what i must do? Or have some advice?

Must be something in your code then, My unity crashs my computer sometimes when I have a big error in my script that isn't picked up (eg: Initiate in Update() -- initiates object every frame ...)
