Open Firefox in Private Mode by Default
Opening a Firefox Private Window is oftentimes the first step persons who value privacy do when they open their browser. That made me think: can you configure Firefox to open in private mode by default? It turns out you can.
about:config
When you type about:config
in the address bar of Firefox, you are brought to a screen listing hundreds of options you can update to customize your Firefox experience. about:config
rightly comes with a warning that by modifying these options you may cause problems with your install; luckily the setting we want to update is simply a boolean.

browser.privatebrowsing.autostart
Update the browser.privatebrowsing.autostart
setting, which defaults to false
, to true
. Updating this setting ensures that Firefox windows and tabs open in private mode. You will need to close and reopen your browser for the updated setting to kick in.
