You can launch applications and programs using the command prompt—And Mozilla Firefox is no exception. You can also use the command prompt to launch Firefox in incognito mode or open a specific website at launch. Here’s how.
To launch Mozilla Firefox using the command prompt, you must already have downloaded and installed Firefox on your Windows 10 PC.
Launch Firefox using the command prompt
Open Command Prompt by typing “cmd” into the Windows search bar and selecting “Command Prompt” from the search results.
In the command prompt, run this command:
Mozilla Firefox will now open normally.
Open a specific site in Firefox using the command prompt
Instead of launching Firefox and then entering a URL in the web browser to visit a site, you can do both at the same time using the command prompt.
Open Command Prompt (type “cmd” in Windows Search and select “Command Prompt”) and run this command:
Replace with the URL of the site you want to visit. For example:
launch firefox www.howtogeek.com
Firefox will launch and open the specified site.
Launch Firefox in incognito mode using the command prompt
Using Mozilla Firefox in incognito mode clears your search and browsing history when you log out of browsing.
To launch Firefox in incognito mode, open the command prompt (type “cmd” in Windows Search and select “Command Prompt”) and run this command:
start firefox -privé
Firefox will now launch in private browsing mode.
