Comment 4 for bug 1887509

@ken-vandine, please don't mark valid issues as invalid - I know hundred of people who got this bug when tried to install software from .deb file downloaded with internet browser, like Google Chrome, Zoom, OnlyOffice, Scratux, Skype, etc. on Ubuntu 20.04 :(
Because when you download .deb file default action in Firefox is "Open with Software Install" (downloads .deb file to /tmp/mozilla_username/ folder and opens that file with Snap Store)

I will be forced to replace Snap Store with original Gnome Software in our Ubuntu-based distribution for Lithuania (see https://launchpad.net/baltix) if Ubuntu developers doesn't want to fix this important usability issue. Sone official Ubuntu derivatives already did this.
