Compared to the other two Tor and Chromium it’s very mainstream.

The popularity of Firefox is a testament to its speed and reliability.

But its also safe to say thatFirefoxs developers care about your safety and privacy.

This doesnt mean that Firefox automatically comes with the best security options, though.

you might get there by clicking on the three horizontal bars in the upper-right corner, then selecting Options.

After the page opens, click Privacy and Security on the left side.

Right away, you will see that thedefault tweaks are not the most privacy-conscioussettings.

Switching from Standard to Strict content blocking means youll basically always be browsing in private mode.

The Options page says that strict blocking can prevent some sites from displaying properly.

Directly below the general content blocking option, you have the choice to block even more tracking.

By selecting Always, youinstruct Firefox to send every website a Do Not Track signal.

Unfortunately, thisdoes not guarantee that any particular website will complywith the request.

press controls for each of these to open up a dialogue box.

Then smack the box next to the words Block new requests.

This guarantees that youll never accidentally click okay on a request for remote access.

As mentioned above,Firefox has a good track recordwhen it comes to privacy and security.

But this isno reason to allow them to gather datafrom you.

Firefox offersfree download for literally thousands of add-onsand online window extensions.

Andmany of these improve upon the above-mentioned privacy controls.

Some noteworthy examples includeuBlock Origin, Ghostery, HTTPS Everywhere, and NoScript.

The first two add-ons are similar.

HTTPS Everywhere makes sure that youronline connections are encryptedwhenever possible.

And NoScript gives youcontrol over the scripts that are often the most vulnerableparts of a websites code.

Firefoxs main options page and certain add-ons can have a powerful impact on the privacy of your web browsing.

you could reveal these tweaks by typingabout:configdirectly into the Firefox address bar.

Youll have to know what youre doing before you proceed.

The web app will then warn you that there could berisks associated with making changes.

Butif you know what to look for, its worth clicking to accept the risks.

One thing to look for (or punch in into the configurations setting search bar) isprivacy.resistFingerprinting.

Another important hidden setting isWeb Real-Time Communication,or WebRTC.
