Connect hosted yahoo boss search to opensearch with browsers

I am running a hosted yahoo boss search website [login to view URL] and want to connect it to opensearch for firefox, chrome, safari and other browsers. The open search can be installed but the connection to the hosted yahoo search does not work. I need some small help now. If the prototype works the programming needed will get bigger next time :) <?xml version="1.0" encoding="UTF-8"?> <OpenSearchDescription xmlns="[login to view URL]"> <ShortName>Example</ShortName> <Description>Example Search</Description> <InputEncoding>UTF-8</InputEncoding> <Image width="16" height="16">[login to view URL]</Image> <Url type="application/x-suggestions+json" method="GET" template="[login to view URL];client=firefox&amp;hl={moz:locale}&amp;q={searchTerms}"/> <Url type="text/html" method="GET" template="[login to view URL]"> <Param name="q" value="{searchTerms}"/> </Url> <Url type="application/opensearchdescription+xml" rel="self" template="[login to view URL]" /> <SearchForm>[login to view URL]</SearchForm> </OpenSearchDescription>
