Using FF v68.8.1 on a Samsung Tab A10 (2019) Android tablet. On the eBay UK site whenever I enter anything in the "search" box, it returns a page saying "service unavailable" along with some links, including one to "try again". Tapping that just returns the same page. I have already tried clearing the cache and cookies (by selecting Settings - Clear private data - Clear now - leaving all boxes ticked). It has made no difference. I also tried the "Cookie Quick Manage" extension - no difference. The same Firefox version on my Android phone does NOT exhibit the same issue. Any ideas please, anyone?
