eBay restricting Webslices to MSIE users, trashing Firefox users
When eBay started implementing Webslices, they did in a special search page ie8.ebay.com. They removed that page a few months ago because they moved the feature to the normal eBay pages. But this has a bad, and I hope involuntary, side effect : Webslices work now only with MSIE and not with Firefox+Webchunks any more. There is something, on the server- or client-side that does client-sniffing probably based on the MSIE extensions to window.external, and eBay result pages are different between MSIE and other browsers.
In MSIE8, all result entries in eBay have a hslice class and a related ID to be detected as a webslice by MSIE8.
In Firefox, the very same page does not have the hslice class. The ID, required by the Webslices spec, is dropped to.
