One of the most used applications on your computer is your web browser. Although Firefox is a great browser that respects the user’s privacy. Using default settings in Firefox can result in some security and tracking flaws. After a few minor changes in Firefox’s settings results in a more secure browsing experience.
Step 1: Privacy & Security
- Open a new Firefox Session, then navigate to the “Menu” button (3 horizontal bars). Located in the far-right corner of the browser window.
- Select the “Settings” option with the cog icon.
- Lastly, click on Privacy & Security.
Or enter about:preferences#privacy into your address bar.
Step 2: Forms & Passwords
- Deselect [Remember logins and passwords for websites] and [Use a master password].
When browsers store passwords for you, they are insecurely kept.
Using a third-party password manager like LastPass or KeePassXC is a better option. Third party password managers sole purpose is to secure passwords. They put a great deal of effort into making sure credentials remain secure.
Step 3: History
- Use the drop-down box next to “Firefox will” to select [Use custom settings for history].
- Make sure all options are deselected EXCEPT [Clear History when Firefox closes].
Those options will clear all saved browsing history data after you close down your Firefox session.
Step 4: Cookies and Site Data
- Select [Accept cookies and site data from websites].
- To the right of “Keep Until” select [I close Firefox].
- Select [Never] from the “Accept third-party cookies and site data” drop down.
These options clear stored cookies from websites after the Firefox session ends.
Step 5: Tracking Protection
- Ensure you have [Always] selected, to block tracking from site to site.
Step 6: Firefox Data Collection and Use
- Make sure both options are unchecked.
Although Firefox is respectful of user privacy. keeping these options unchecked, prevents Firefox from exporting session data for their use.
