Created by a non-profit organisation Mozilla, Firefox is an open-source browser that is built keeping your privacy in mind as it offers relatively more transparency and shows user activity through public data reports weekly. Launched in 2004, Firefox has one of the biggest developer communities, which is striving to make Firefox better with add-ons that allow users to customise their browser according to their needs, add-ons offer a more personalised and secure browsing experience.

With over 250 million users worldwide, Firefox makes up 4% of the total Internet traffic. Out of this, one-third of the users have an add-on installed on their browser. Due to this high demand for add-ons, the Firefox add-on library is loaded with applications that enable users to customise their browser, improving the aesthetics and privacy of their browsers.

To help you get the most out of your browsing experience while using Firefox, we have curated a list of 10 add-ons, which will make your experience more rewarding.

Dark Reader

When it comes to improving the aesthetics of your browsing experience having a dark theme for all the websites you visit goes a long way. This is where dark reader comes into the picture, it forces a dark theme on all the pages you visit. Not only this the add-on allows users to customise brightness, contrast, sepia filter while using the application. It also allows users to create an ignore list for the websites where the dark theme should not be implemented.

Facebook Container

Most of us are familiar with the fact that Facebook collects data when we use the application in our browser, but this is only partially true. Facebook also tracks you on the Internet when you are not using the app through its like button and the Facebook pixel.

10 Firefox Add-ons for increased privacy and a better browsing experience

Every time a user interacts with the like button or the pixel, information is sent to Facebook and linked to your profile. To prevent this cross-platform tracking, you can use the Facebook container. This add-on prevents Facebook from tracking you on the Internet by isolating your Facebook profile in a container and deleting all Facebook cookies and logging you out of Facebook when you close the container.

As this add-on restricts your Facebook profile to a container, embedded Facebook comments and like buttons will not work when opened in tabs other than the Facebook container to prevent cross-platform tracking. In addition to this, websites using Facebook authentication for login might face some issues as well. Using Facebook share buttons on other sites will also open a new container to prevent Facebook from tracking you.

The Facebook container was created by Mozilla Firefox developers keeping user privacy in mind, and the add-on does not store user data. Using this add-on with your browser will help limit the data Facebook can collect from your browsing habits which is always a great thing to have.

Doing this increases the speed of your browser as memory resources are used by active tabs and scripts running on inactive tabs do not use your browser’s computational power

Auto tab discard allows you to select the websites which should not be discarded and prevent tabs from getting discarded when they are pinned or media is playing in those tabs.

Firefox Multi-Account Containers

Retargeted advertisement is all over the Internet and once you put something in your shopping cart, a similar product will keep following you around the Internet for days.

10 Firefox Add-ons for increased privacy and a better browsing experience

To make retargeting possible, advertisement companies create online profiles of users through third-party cookies and browser fingerprinting. Using these techniques companies can make accurate profiles of users and browser compartmentalisation is one of the only ways to solve this problem.

Although browser compartmentalisation can be effective, using multiple browsers every day can get a little cumbersome. To solve this issue, you can use the multi-account container extension for Firefox.

This add-on allows you to compartmentalise your tabs into different categories by isolating them in different containers. These containers are responsible for managing cookie data and all other information pertaining to the tabs open in them making each profile an independent browsing entity. Due to this, different containers can be used for different tasks like work and shopping so that advertisers cant track you and bombard you with targetted ads.

When a container is closed, all the cookie data stored for the websites running in them is deleted, further increasing the privacy of the add-on. Multi-account containers also allow you to select a profile for particular websites so that they don’t open without the protection of a container. Therefore if you want to enhance the security and privacy of your online presence multi-account containers is a must-have.

This application also helps in organising your tabs as it colour codes all your tabs and helps in easy management as well. The add-on is developed by Mozilla Firefox and does not send any data to Mozilla.

Most of the websites you visit on the Internet make use of several different libraries so that they can function properly. Sometimes the libraries these websites use are not hosted with the website and are not available on your system. Therefore for the website to work properly they need to be downloaded to your browser.

10 Firefox Add-ons for increased privacy and a better browsing experience

To download these libraries, your browser sends a request to content delivery networks which host these libraries for free like Google hosted libraries and jQuery CDN. Every time your browser sends a request to get these libraries it sends your browser headers to the CDN giving it your IP address and other information alongwith it.

Decentraleyes is an add-on for Firefox which stores these libraries locally on your system so requests are not sent to third parties to get libraries increasing your privacy while browsing. Also, as the libraries are locally stored on your system it could speed up your browsing experience as well. If a library cannot be found locally and a request has to be made to a CDN to get it, Decentraleyes removes the metadata from the request and then sends it to the CDN, hence increasing your privacy.
