Many development tools will automatically open a browser upon start-up (e.g., fire-up a react-app, or a jupyter Notebook). I only have `firefox-dev` on my machine. I have created an alias firefox -> ../path/to/firefox-dev/bin. I had to do this because `firefox-dev` nor `firefox` worked (command not recognized). Finally, my mac os preference has been set to `firefox-dev`. Despite having set the `env` variable `$BROWSER` set to the alias, the desired behavior (above) is not happening. All in all, it would be great to have expanded documentation on how to fully configure your mac to use `firefox-dev`. Thank you in advance for any help on this useful part of my workflow. PS: I love this app. Nice job! - E
