ebay.com doesn't fully support Firefox for iOS. Firefox throws a big warning message on all subpages. It looks like the user agent Firefox for iOS isn’t fully supported, yet. There is not much you can do. You can get in touch with the webmaster.

Could you share some website that show Not supported browser?

Paypal won’t let me transact with Firefox and YouTube now has a message they’ll stop supporting my browser soon and to update. I click, routed to Mozilla, click, routed to Firefox at App Store, click, just opens my browser. Thanks
