The new stable version of Firefox (70) brings a new security feature. It's called Social Tracking Protection. Let's see how it can help:
It's no secret that social networks track us and collect as much information as possible. The goal, of course, is profit.
What average internet users may not know is that social networks can track us even when we're not using them. To do this, they use trackers embedded in other websites. This way, they can monitor our browsing habits even if we're not logged in or registered on the social networks. 
Tracking blocking has been around for a long time in modern browsers, and Firefox has different tools to protect you from this social media behavior.
The latest version of the browser released by Mozilla is Firefox 70 and one of the highlights it contains is Social Tracking Protection (available in Enhanced Tracking Protection).
Social Tracking Protection refers to the tracking we encounter on social networks like Facebook, Twitter, and LinkedIn. These networks distribute tracking cookies so they can track us across the websites we visit. The new Social Tracking Protection feature is an arsenal of tracking protection tools in Firefox that will help improve our privacy while browsing the web.
What you need to know is that Social Tracking Protection is enabled by default in Firefox on all platforms, so you don't need any additional settings for your protection.
Mozilla states:
Firefox blocks the most common trackers from Facebook, Twitter, and LinkedIn
The default browser setting offers a good balance of protection and performance. You won't experience any problems while browsing the web.
On the other hand, if you use the strict level, many more trackers may be blocked, but there is a risk that pages may not load properly.
Mozilla also states that despite Firefox's social media tracking protection, there is a chance that some tracking will occur and there is nothing you can do about it.
“Social media companies will still be able to collect data about you if you use their services to log in to other websites (with your Facebook or Twitter account).”
