I'm using Google Chrome and I'm having no issues.

For the record, if you don't "hit" an opponent - that is to say, if someone isn't online, also playing the game, for you to fight - you have to keep clicking the "Join the Fight" button until you do. It can take anywhere from a couple to a dozen refreshes, depending on how things are going on the site. Not sure if that might be the issue, but I just thought I'd put it out there. Just waiting on the "It has been # seconds since you last saw battle" page won't get you an opponent.
