Opera is faster than firefox?

So I was fooling around with speedbit video accelerator and youtube the other day, and I found something funny.

Normally, it would take a 5-minute youtube video to finish downloading on my computer in 25 seconds with firefox.

However, it took me 3 seconds for another 5-minute video to finish downloading on my computer with opera.

I've tried this multiple times, and opera always ended up beating firefox by a mile.

So maybe firefox is losing its good ol' touch.
