Well, I can load the website up fine with my computer, so let's see if it can get it working on yours.

Try clearing your Firefox cache. something may have been corrupted in it that is preventing your website from loading. Read How to clear the cache for the how-to.

Update your Firefox to version 11. Updating Firefox has some easy steps for that as well.

After doing that, try to load the website up again. If it still doesn't work, try starting Firefox in Safe Mode.

Thanks - but none of those helped. I am glad to hear that it is my installation and not the site.

Alright then, let's try starting your Firefox up in Safe Mode.

Also, you may want to look at these articles:

Firefox cannot load websites but other programs can is a generic page for Firefox not being able to load websites.

loading web sites https://support.mozilla.org/en-US/kb/Error loading web sites provides some more specific instructions to your issue.

And finally, Firefox never finishes loading certain websites provides two more steps you can try for troubleshooting.

The Game listing tab on that page gives me a problem with Firefox using 100% of a processor core and stalling for some time (at least 20 seconds). It keeps showing Connecting during that time on the tab, but the throbber isn't spinning.

Yes, this is odd and perhaps the source of the problem.

In the Excel spreadsheet, the Game Listing worksheet goes to column AT. However, when I save the file through a macro I wrote, it has many, many more columns, as if I use the maximum.

I have tried to figure out, unsuccessfully as of yet, why that is the case.

Thank you.
