When I download a file with firefox, it always asks me with what program I want to open it with, even when that type of file is recognized by the system, and I can double click on it in Nautilus and have it open properly.
This is an example with a deb file, which opens with Ubuntu Software center (as it should) when I double click on it in Nautilus.
I do not want to look for the required program in /usr/bin or whatever in the Firefox dialog, I want Firefox to recognize my system preferences. What I resort to doing now is choose "Download", open Nautilus and double click on the file...
Why can't Firefox recognize my system settings, and how do I get it to?
