Firefox 1.5.0.2 and ebay

For the last couple of days now I have noticed a problem with firefox
and ebay. When I go to a particular catagory such as photography and
enter a key word such as Minolta in the catagory search box it works
fine usually defaulting to ending soonest. When I go to the sort by
box and choose say time: newly listed nothing happens. However it
works fine in IE.
I have 3 machines running firefox and it's doing the same thing on all
3.
Has anybody else noticed this problem??

I have contacted ebay but have not heard back from them.

 

I have a similar problem with this weather site from Ecuador, I can
never get the data using Firefox. However, it's because it has not been
written using the standard html convention.
