12 coolest Firefox About:Config Tips and Tricks to protect your Privacy

Protect your privacy in Mozilla’s Firefox using these 12 cool About:Config tips and tricks

Everyone is worried about privacy these days and most browsers leak your personal browsing history for variety of reasons. Though you cant control all that the browser can snoop on you, you can make certain changes in the way your browser behaves to control the same.

If you are using Mozilla’s Firefox browser you can add/edit certain features to enhance privacy using the awesome About:Config.

The about:config page contains most (if not, all) of Firefox configuration options. It is so far the most effective, and the most powerful way to tweak and enhance your Firefox performance. Here are 12 most important tweaks that you should know to protect your privacy while browsing on Firefox.

How to access About:Config in Firefox :

In your Firefox, type about:config in the address bar.


You will be shown a warning page. Click the “I’ll be careful, I promise!” button to proceed.


On the main page, you will see a long list of configuration entries. Enter the name of the key you want to update in the “Filter” field. The list will narrow to only the entries that match your keyword as you type.

To modify the value, simply double click on the entry value field and update the entry. That’s all!

  1. I stupidly refreshed Firefox (51.0) so had to find and reset per your instructions above. However, “browser.safebrowsing.enabled” is no longer there. Can you please advise the revised setting here?
