Click on the "preferences" link, and select "delete your cookies". Do so.
If you have more than one browser window open, close the extras. Leave TheFiringLine and go to another site. Return. See if the folders are now working.
If not, it's time for last ditch measures. Shut down your browser. Do a search on your system for cookies.txt and delete it. Empty your recycle bin, and restart your computer. Visit TFL again. It should be working now.
If you are using AOL, all bets are off, as their browsers are buggy at best. 99% of all UBB problems come from people on AOL.
