Thanks FredMcD for your answer. Now,i think i found the culprit! It's a specific cookie (named "nonsession") under ebay.co.uk (see attached image). Btw, i have no problem if i connect through ebay.com! Problem appears only under ebay.co.uk Whenever i remove this specific cookie, listings appear just fine! But the problem is that if i close firefoc and restart it,the problem re appears and i need to remove cookie again! I suppose there is a much more practical solution of removing the dammed cookie each time by hand! :-)

A cookie, basically, is used by web sites to store options and information for that site. It could be one of the site options is bad.

Go to the Mozilla Add-ons Web Page {web link} (There’s a lot of good stuff here) and search for what you want.

What you want is a cookie controller, something that removes that one (not all) cookie for you. I do not use them, but I found this list;

This is a list of help files about cookies. https://support.mozilla.org/en-US/search?esab=a&w=1&q=cookie

Thanks again FredMcD! I just install cookie controller and now everything is ok!

That's good to hear. Happy computing.
