Could not find the Mozilla runtime
I try to run sage: notebook(), or some other notebook with name between the parenthesis, but I get the nessage 'Could not find the Mozilla runtime' and Sage stops.
What is the solution? sagemath is v7.3.5 sage-notebook is v0.13.3
I'm using the Firefox web browser, v49.0.1
What operating system? How did you install Sage?
I'm using arch linux (antergos), and there are some packages for sagemath in this distro. If I type in firefox: localhost:8080, then it opens the notebook, but previously it needs to reset the admin password.
