Using Flash with Vista without internet explorer crashing all the time

I've just had to disable Flash9c.ocx becaue it kept crashing internet explorer. Now I can't watch you tube, or design my own Simpsons character. What's the solution, anyone got any ideas? SHould I just start using Firefox

I hardly ever use IE i only use when i have to. Mozilla is the way to go, are you using IE 7? have heard a few complaints from my users who have upgrade.
