This has been happening to me all Saturday.I use Mozilla Fire fox as a browser (have done for 2 years) .If I use Google Chrome I can view the listings, if I use Firefox I can't, E bay can't offer any further help after my call to them this morning and told me it was my browser Firefox issue.I stopped using Chrome as a browser 2 years  ago (issues printing e bay docs, invoices etc), I guess someone has been tweeking, maybe even twerking something and we will all just have to wait until they fix it !
