So I have a dual monitor set up with two firefox windows on each monitor.

When I load up SC2, the game constantly minimizes every five seconds to the firefox window on the secondary monitor.

I can either close down firefox completely or wait a minute or two for the game to stabilize before it will cease minimizing.

Is there any reason to why this is happening?

Hello Krieger

These sorts of issues usually occur when another program takes focus away form the game.

Do the issues occur if you close down firefox?

Try starting up Firefox in safe mode

Click on Start, Programs, Mozilla Firefox, Firefox (Safe Mode)

And see if the issues still occur. If it is resolved than one of the addons is the cause.

You may want to try experimenting with the various addons in order to determine which one it is. If you are able to find out please post the information in the bug reporting forum. You may also want to try to notify the creator of the addon.

You may want to start with the less popular addons. The more popular the addon the more likely the issue would have been reported already.
