As a Website Developer/Programmer, I have always preferred either Firefox or Chrome. Chrome is great for general Website browsing, but Firefox is much more stable, and much more reliable as far as visiting sites, and getting the intended view/functionality of the site.
Sadly, I currently am running the newest version of Chrome, IE9 Beta, and Firefox 4 Beta. Out off all of these, IE9 is a HUGE improvement over the previous IE versions, while I have to say so far, I am surprisingly disappointed with the Firefox 4 Beta. It does not support somethings that it should, but hopefully these issues will be addressed, and fixed before the final version is released. As far as the new Chrome goes, I have yet to have any issues out of it, so my suggestion to you is if you have any extentions installed, try disabling them, and then try to access the website again. If you don't have any extentions installed, then I would suggest uninstalling your flash player plugin, and reinstalling it, though I don't know the site, so I can't tell you for sure.
