I am using Firefox 126.0 under Windows 10. I am trying to add search engines to the search toolbar. (Just to be clear, this is the search box that appears ''below ''the address bar, not the address bar itself.) I followed the instructions [http://mzl.la/1VShhHu here]. That worked fine for Wikipedia, Google Maps and YouTube. Then I tried to add Amazon UK. The Amazon icon is now present in the search box, but when I select it, I see this message: Firefox could not download the search plugin from: https://d2lo25i6d3q8zm.cloudfront.net/browser-plugins/AmazonSearchSuggestionsOSD.Firefox.xml I have no idea what this means or what to do about it. (I also tried adding it from Settings > Search > Search Shortcuts, but Amazon does not appear on that list of search engines [unlike on my other computer]. I clicked "Find more search engines", but that brought up a list of 5,192 extensions, most of which seemed not be related to searching.) Thanks in advance for any help or suggestions. Mike
