I installed Firefox Dev on Ubuntu 18.04 per these instructions (marked as correct answer):
Error while installing Firefox Developer Edition on 18.04.1 LTS
When I search for Firefox Dev, Ubuntu only turns up the Firefox browser.
And in Terminal when I type firefox-dev --version
I get "No such command".
which firefox-dev
in a terminal? That should list the path to the application if it is installed. You might also trylocate -b firefox-dev
. The packagefirefox-dev
is available in Ubuntu repositories, so this method of installation you linked above may not be the best method:sudo apt update
followed bysudo apt install firefox-dev
should be all you have to do. – Nmath Jun 12 '19 at 22:18
