I want to run the latest version of Firefox rather than ESR. So I downloaded the tar file from Mozilla and installed in the Debian 11 template. There is now a firefox.desktop file and a firefox-esr.desktop file in usr/share/applications. I can refresh the applications in the Qube settings and I can launch Firefox in the template.
In the app qubes however, it ain’t working. Here I also have two Firefox options but launching the new Firefox still brings up the ESR version.
probably go by first cloning the vanilla template, then also add sid(unstable) source to debian and install firefox (someone at debian/firefox) provides latest firefox: Debian -- Details of package firefox in sid (removing firefox-esr packge in that template would probably help avoiding mix ups)
I’m not sure I want to do that just for the one app. Though apparently there is such a thing as “apt pinning” that can be used to install just one app without enabling the entire Debian sid repository.
