Always Start Mozilla Firefox in Private Browsing Mode

 

How to Always Use Private Browsing Mode in Firefox

First, open Firefox. Click the hamburger icon in the upper-right corner of the window. (A hamburger icon looks like three horizontal lines sandwiched together.)

When a menu pops up, select “Options.”

On the Options page, switch to “Privacy & Security” settings by clicking on the padlock icon in the sidebar.

On the “Privacy & Security” page, scroll down until you find the “History” section. Click the drop-down menu beside “Firefox Will” and select “Use Custom Settings For History.”

With “Custom Settings” selected, look beneath the drop-down menu. Check the box beside “Always Use Private Browsing Mode.”

Upon clicking the checkbox, Firefox will ask to restart the browser. Click “Restart Firefox Now.”

Once Firefox restarts, private browsing mode will always be enabled.

To confirm this, return to Options > Privacy & Security > History. There should be a check mark in the box beside “Always Use Private Browsing Mode.”

Now you’re good to go. Just remember to close all of your browser windows when you are finished with your session.
