...I am not sure what I did, but I somehow blocked all items hosted on my server (wcyt.org) from being seen on Firefox.

So when I log on to www.wcyt.org from just this computer, I see nothing but text using Firefox...on IE it works just fine and on Firefox from any other computer I have tried it works just fine too.

I have uninstalled, deleted, reinstalled, searched for updates and everything...to no avail.

Any ideas what I could have done to cause this....and how to fix it?

"everything"? Did you try cutting off the tail of a white goat on the seven-road crossroads at full moon and feeding it to a black cat?

When you uninstalled and deleted, did you actually delete the Firefox folder from your profile directory (Documents and Settings\username\...)?

I just brought up the site on Firefox v2.0.0.4 and all I saw was text and the yellow bars framing the sections. Then I brought up the site in IE6 and saw the same thing- except the resolution was greater.

There was no notice of a plug-in being stopped on either browser. What is it you're missing?
