As of FireFox 109, Firefox is opening RCV files as links instead of defaulting to binary download files. This binary file is not a viewable file and MUST be download.

This problem can occur when the server isn't configured for the .rcv file extension and sends it with one of these headers
As a workaround, you can right-click the link and use Save Link As... to bypass automatic handling.
Also, if my diagnosis is correct, you can create a custom Content-Type override using my add-on, Content-Type Fixer. More info: https://www.jeffersonscher.com/ext/content-type-fixer.html (see the Roll Your Own section).

This problem is only occurring in FireFox. 109 Chrome and Edge browsers do not have this issue.
