Firefox 74 has an official Facebook Container add-on that keeps social media links from tracking your browsing activities on the web. It can automatically block any Facebook tracker when outside of Facebook to increase your privacy online.
How the Facebook Firefox Container Works
The Facebook container works by isolating your Facebook activities into instances that are completely separate from your browser, which Firefox calls a container. When you install Facebook Container, the Firefox extension deletes your Facebook cookies, removes you from the site, and closes all open Facebook tabs. This is a free browser extension made by Mozilla itself.
Once activated, you are free to navigate to Facebook as usual. When you do, you will see a blue line under any Firefox tab. This shows that the container is active. Everything related to Facebook in that container is permitted. Everything related to Facebook outside the container is blocked. Every non-Facebook link that you click inside the container will open in the normal Firefox browser tab, outside of the Facebook Container.
Any website that requires a Facebook login, or accessing its contents, will not function properly if there is one. This is the exact purpose of the add-on: to stop Facebook-related activities so as not to disturb you or track you during your normal search activities.
Remember: This add-on does nothing with the information that Facebook already has, nor does it interact with Facebook’s intrigue in the container. Additionally, this add-on might conflict with the Multi-Account Container add-on, which allows you to place one or more websites of your choice into the same container. You can use the color-coded tab to operate on different websites without a tracker, or in many instances of the same website with the same account.
How to Install and Activate Facebook Containers
Visit the Facebook Container page on the Mozilla Add-Ons site in Firefox to install it. Or, navigate to “addons.mozilla.org” in Firefox and search for “Facebook Container.” Once you are on this page, click “Add to Firefox.”
The message “Add Facebook Containers” will appear. Click “Add.”
You can see if a tab has an active Facebook container by looking for a black line under the tab text.
How to add exceptions
The container isolates your Facebook activity in a specific part of your browser. Facebook cannot track your search activity through the Facebook button on other websites. However, you might sometimes want to interact with your Facebook account on a different website.
If you want to exclude a site from this restriction, you can add that website as an exception and allow it to interact with Facebook. To do this, navigate Firefox to the website. Click the Facebook Containers icon and select “Allow Sites In Facebook Containers.”
Click “Allow,” and the page will refresh with this new setting in place.
With this setting, Firefox can give you a browsing experience that doesn’t throw new ads at you based on what you last saw on Facebook.
