Numista opensearch file seems to be incorrectly formatted. [solved]

When trying to add numista as a search engine in firefox I get the following error:

Firefox could not install the search engine from: https://en.numista.com/opensearch_desc.php

Looking at the browser console I see:

XML Parsing Error: XML or text declaration not at start of entity

Looking at https://en.numista.com/opensearch_desc.php directly it seems the file has a newline at the beginning which may be what is causing this error.

Thank you for reporting the issue. I removed the new line at the beginning of the file and it seems to be working again.

Thank you for reporting the issue. I removed the new line at the beginning of the file and it seems to be working again.

Thanks!  I just tested it and can confirm it's working for me in firefox.
