I'm running Firefox 3.6.13 and if I click on a link to open a new window nothing shows up - i.e. if I click on 'enlarge' on an Ebay auction photo a new windoiw opens but it's blank inside. Any ideas please? I've tried uninstalling and re-installing but no joy. I'm sure I'm missing something obvious but being a bit of a numpty can't work it out. Thanks, Joe.
