Hi, On the openSUSE package search page, https://search.opensuse.org/packages/ (which has no entry for Leap 15.5 yet) I get a button named [AppStream Install]. Clicking there nothing happens. The URL is: appstream://com.github.louis77.tuner Obviously, FF doesn't know what to do with that, and doesn't even say I don't know what this is. The wiki page on it: https://en.opensuse.org/AppStream Doesn't provide useful information, like how to install such a package on Leap or what to do with FF. I have done this on another computer, but I'm not on that location and don't have my notes on it. Google wants to teach me on how to create them, which is not what I want. -- Cheers / Saludos, Carlos E. R. (from Elesar, using openSUSE Leap 15.5)
