[PLUG] What's missing from my Firefox?

[John Jason Jordan]

Firefox 3.6.17 on Fedora 14 x86_64, everything up to date.

I am finding that Firefox cannot find pages on certain links. It
appears that the link that Firefox cannot find is a link that ends
in .asp, not that I have any ken what .asp means. For example, go here:

http://corpus.byu.edu/coca/

In the column to the left there are question marks for several of the
items. Hovering over the question mark reveals that the "link" ends
in .asp. Every one of them results in an Atlanta error.

Using Opera all the links work as expected. Apparently Opera can handle
links ending in .asp, while Firefox cannot.

What do I need to add to Firefox to make it work with these links?
