What is Firefox Containers and How to Use it?

Learn how to install and use the Firefox Containers for better privacy and security. You can organize and manage the container for browsing websites.

Cookies have become an integral part of our online browsing activities. Be it for storing our login information or helping out the trackers, their job is spread across a large field of view.

Let’s try and understand it with the help of an example. Suppose you searched online for a formal shirt. Later on, you open Instagram and while scrolling through the feeds, you get to see the ads related to that same product. Well, this is no coincidence of sorts.

What happened was when you were searching for a product, the cookies were busy tracking your activities. They then interacted with the social media cookies and passed on the information related to your recent query.  As a result, the latter set of cookies knew exactly what type of targeted ads they needed to display. The benefits?

Well, it leads to a higher probability of your interaction with these ads as opposed to any random ads that Instagram might have shown. So what can be done to stop this from happening?

The first idea that might come to your mind is to block all the trackers. While Firefox does provide the option to disable JavaScript, but in some instances, it might have a few downsides as well. For example, since most trackers are JavaScript-based, the browser will tend to disable all these scripts.

Unfortunately, a large chunk of the websites is also dependent on these JavaScripts for their normal functioning. So blocking these scripts might have adverse consequences on that site. Furthermore, blocking cookies would also log you out from all the sites, since they are responsible for storing this login information.

To overcome all these issues, you shouldn’t look any further than Firefox Containers.

What are Firefox Containers?

Firefox Containers are used to create segregated cookies belonging to different domains. For example, there will be a standalone jar just for social media cookies, the next one for shopping, another for banking, and so on. These cookies remain confined to their “jars” and wouldn’t be able to interact with cookies belonging to other domains.

As a result, the trackers part of the Google search wouldn’t be able to pass on this information to the social media trackers and hence you wouldn’t be bombarded with so-called curated ads on your Facebook profile.

Furthermore, if you are signed in to Firefox with multiple accounts, then you could use this feature to segregate your work account activities from personal ones by storing them under separate containers.

All in all, it proves to be an effective way of minimizing the tracking of your browsing activities and hence leading to enhanced online privacy.

Install Firefox Containers

Apart from the Firefox container, the browser also has a separate Facebook Container. So what’s the difference between the two? The former has a much broader field and deals with trackers across all the sites. However, if your primary concern is just related to Facebook, then you could also try out the Facebook Container.
