Hey guys, I was wondering whether you could help me with a small problem that I am having with my first Flash animation. 🙂

I’m using CS4, and when I export the SWF and view it in Firefox, it skips/lags at certain points in the animation (specifically during some of the fast, “zooming out” text tweens - you’ll see what I’m talking about if you watch it below). The odd thing is that it appears to work just fine in IE.  
The animation isn’t **that** complicated, but it does have a fair amount of text tweens.

You can view it here: [http://name.here.erikswan.net/mighty](http://name.here.erikswan.net/mighty)  
The FLA is here if you want to take a look: [http://www.erikswan.net/mighty/You%20Are%20Mighty.fla](http://www.erikswan.net/mighty/You%20Are%20Mighty.fla)

I was wondering if it is slow, choppy, or laggy for you and whether there is anything I can do to optimize it and make it run as fast as possible.

Thanks, I really appreciate your help. 😃
