The banner advertisements from Grandchase.net make my computer run extremely slow.

These are the ones that are heavily animated and show panels of small characters being opened and closed and changed (from what I can tell). They are primarily black and red in color.

Firefox nearly locks up, and I have trouble switching between tabs.

It’s bad enough when there’s one on a page, but usually there are two or three displaying at a time.

Is there any way these could either be toned down or removed in favor of other advertisements?

I have no idea what they’re advertising, but the way they’re sabotaging my browser, I’m not sure I want to know.

I’d rather not spend brownie points just because one advertisement screws up my computer.

I don’t mind the others, and in fact, have been interested in a few of them.

Anyone else had problems like this?
