Can't set Google UK to default

I have recently come back to try FF again, but I now remember why I stopped using it last time.

The following extension is missing:

Which means that there is currently NO WAY for me to set my search default to Google UK.

When I search in the omnibox, it always directs me to

I’ve got UK set as my language and location for the OS and FF.

Any idea?

I guess a lot of older style OpenSearch plugins (.xml format) were not migrated to the new style (.xpi format).

Note that I didn’t put the “G” icon in there at this point. Hope to add that later.

Update: a G .uk icon has been added.
