After reading some of the users reviews of Firefox3 over at CNET I would'nt go near it with a hundred foot pole.
Any other suggestions ?
The message you are conveying to us is:
1) My favorite site doesn't work.
2) I don't want to upgrade my browser or use a new one.
3) I can't be bothered to test my flash player!
4) Please, ComputerHope, use your voodoo to magically make it work!
That's the same as saying something like this:
1) I use rabbit ears to watch TV.
2) It's late February 2009
3) MY SCREENZER IS BLANKORZ!
4) I DON'T WANNA CONVERTER BOCKZ!
5) Please, wave a magic wand to make my analog TV work with a digital signal!
Test your flash player like Broni said. Failing that, get IE7, Firefox 2 or 3, or some browser that's compliant with the site. We have no magic wands here that we can talk about without making the website Rated R or worse.
