I am running Firefox 15 on Ubuntu 12.04.
If I go to a website with a
.deb link, Firefox downloads the file, then tries to open it with
gedit. If I use Nautilus to open the
.deb file, it runs it in either gdebi or Ubuntu Software Center (I've experimented with both).
Oddly, no matter what I've done I can't seem to get Firefox to believe that debs should not be opened by
gedit. See below from my
mimeapps.list. Also, there are no references to my
.deb files in
