If you are tired of losing data on the Internet, Firefox and its privacy tools can protect you and your information when you visit websites. The threats that Mozilla's Firefox Web browsers for Windows and MacOS can protect you include trackers that track your browsing history, cryptosers that use your device's crypto-currency-aware device, and fingerprints that you identify from your device. Uniquely identify their settings and apps. [1
Taken together, this little information can form a unique set of features about you and your computer that allow advertisers to identify your person. How to Protect Your Privacy with Firefox's Privacy and Security Settings
How to Use the Tools for Blocking Content from Firefox
Firefox 68 can protect you from Web sites that collect information about you without your consent, as well as from cryptometers and fingerprints. You can check which version of Firefox you are running by selecting Firefox from the Firefox menu. (The EFF, a nonprofit privacy officer, has a sobering tool to help you determine if you're losing fingerprint data.)
Blocking trackers can also cause some sites to stop working, so in Firefox under the privacy settings select a balance between protection and usability.
1. From the Firefox menu, choose Settings. (You can also get here by clicking the Hamburger menu on the right side of the toolbar and selecting Settings.)
2. Click Privacy and Security in the settings window that appears.
. 3 Select which privacy setting you want to use:
- Default Protection blocks trackers in private windows and third-party tracking cookies.
- Strenger Protection to block trackers in all windows and third-party tracking cookies.
- Customize lets you specify exactly what you want to block, including crypto-germs and fingerprints. In an upcoming release, Mozilla will block cookies by default with third-party trackers. However, you can now enable this advanced tracking protection if you want to check it out by enabling cookies and then choosing "Third party tracker" from the popup menu.
. 4 After you have made your selection, the button "Reload all tabs" is displayed. Click to apply your new tracking settings.
(If you do not already know Firefox, Mozilla will turn on advanced tracking protection by default when you use the browser for the first time.) For existing users, Mozilla will enable protection in the coming months.)
Note : You may want to tweak your privacy settings if you find that some of your favorite sites are behaving strangely after you've blocked trackers.
You can also select the Do not check here option to signal to websites that you do not want to be tracked, but that the sites do not need to comply with your request. Turning on "Do not track" can be one of the things that advertisers use to scan your browser. If you'd like to take the next step to protecting your privacy, you can look at using a VPN and see what permissions you grant to apps.
