I have a program launching a website via the following command.
cmd \"start /max http://url.com\"
When launching a website via this method
Working from VaLo's answer:
cd %directory to browser% %browser's name to main executable (firefox, chrome, opera, etc.)% https://www.google.com
start https://www.google.com doesn't seem to work (at least in my environment)
start https://www.google.com
