In Ubuntu I used
sudo update-alternatives --config x-www-browser
to set the default internet browser manually.
In Manjaro I get:
sudo: update-alternatives: command not found
I have set Firefox as the default in its settings and want it to stay so.
After installing Chromium, the default browser is now Chromium, although I reconfirmed Firefox as such and in Chromnum settings it says: "Chromium cannot determine or set the default browser".
How to make Firefox default browser?
x-www-browser, what is “changing the linked binary” supposed to mean? Are you trying to change the default browser? That depends on the application that launches it — I don't think Manjaro has a system-wide default (and it's more of a user preference anyway). What application are you interested in?
