Can't add search.garudalinux.org as Firefox search option

[praseo]

I would like to default all searches to whoogle.
When I try to do what @anon4516988 suggests for https://search.garudalinux.org, I get the following error message

Firefox could not download the search plugin from: https://search.garudalinux.org/opensearch.xml

Am I missing something here?

No; something is broken on the server:

Just tried after doing a change, does it for you as well?
