Any callsign lookups on the QRZ website ( i.e. https://www.qrz.com/db/A1BC ) will be redirected to the HamQTH page ( i.e. https://www.hamqth.com/A1BC ). The use case for this add-on is when you are not using the QRZ website but instead HamQTH and want to ensure that 3rd party programs that open the QRZ page of an amateur radio callsign will instead open the corresponding HamQTH site.
Clicking on the extension button will toggle disable/enable the redirection.
