Top 10 Key Extensions In Chrome And Firefox For Privacy And Security

Nowadays online privacy is one of the topics of greatest debate for some years. This is mainly due to the cases of Facebook and Cambridge Analytica, as well as the data collection topics of Google and Amazon. Given this, more and more users are seeking to control in the best way possible the amount of data that companies collect on them.

It is not an easy task. Fortunately, we have tools that help us limit this data collection, and even decide what type of data is collected while we surf the Internet. In this case, the extensions for our browser are the best and simplest tools for this type of situation.

For this reason, today we will take a tour of the 12 best extensions of privacy and security for Chrome and Firefox that we can install to protect our data.

Privacy Badger

Undoubtedly one of the best anti-tracking extension is Privacy Badger, which is a project of the Electronic Frontier Foundation (EFF), a non-profit organization that focuses on the rights of freedom of expression in digital media.

Privacy Badger offers us a system of blocklist where it shows us the web pages that are following us, offering us the possibility of blocking all or a part of them at any time. This extension does not block all the content, only the tracking scripts that are kept there in our browser all the time.

Download Privacy Badger.

HTTPS Everywhere

Another extension that comes from the EFF in collaboration with the Tor Project. HTTPS Everywhere is a great tool that allows us to connect to websites using always a secure HTTPS link. Although many sites are improving the implementation of HTTPS, there are still some that continue with HTTP by default, which puts our information at risk.

Download HTTPS Everywhere.


Ghostery is similar to Privacy Badger but with a better interface and a little more options. What this extension does is show who is tracking our browsing on the internet. It detects cookies, blocks trackers, speeds up loading times and, he says, protects our data. An important point is that Ghostery offers us details of each tracker so that we can decide if we want to block it, since it does not do it by default.

Download Ghostery.


Another of the extremely useful extensions to protect our privacy is Blur, a tool that allows us to protect all our personal information online. Blur saves, encrypts and organizes our passwords. It also blocks companies from collecting data about our online activity, including trackers. It keeps encrypted data such as our credit card, passwords, and email protected. Thanks to this, sites like Facebook will not be able to track us.

Download Blur.


Disconnect is another extension that allows us to block trackers in a simple way. Its interface in the best of all the options and also, affirm that it is able to find and expose the so-called “invisible trackers”, which keep track of our activity even if we are not visiting that web page. It also ensures that it blocks those pieces of malicious code that there is internet, and we can always customize the blocking level.

Download Disconnect.


uMatrix is ​​not known for having the best interface, but that does not stop us since we are facing the best firewall for Chrome or Firefox, which promises to protect our navigation and personal data by blocking scripts, iframes and unwanted advertisements. In addition, it shows us details of the web pages to know if we can trust them or not according to the information they request.

Download uMatrix | Chrome | Firefox


We are before one of the most popular and popular password managers today. LastPass not only manages our passwords securely but also other sensitive data such as our credit card information. But beware, here it should be noted that LastPass does not have a good record in terms of security since on two occasions it has presented a failure that allowed access to the passwords of its users with a single click.

Download LastPass.

Facebook Container

This extension is only available for Firefox, but it makes it a great tool to visit Facebook. Facebook Container isolates our identity and movements in a kind of independent drawer, which prevents Facebook from tracking our activity on other websites using third-party cookies. This means that Facebook cannot spy on us, and we will not receive ads according to our browsing history. For this extension to work properly, the ideal is not to use Facebook on the mobile and not have the application installed.

Download Facebook Container (Firefox only).

DuckDuckGo Privacy Essentials

From the creators of the popular search engine DuckDuckGo, we get your extension of privacy that will help us protect our personal data while we browse the internet. This extension blocks the hidden trackers of web pages and loads encrypted versions whenever possible. Even when we fall into a website with bad privacy practices, we will be notified and a rating assigned to each website.

Download DuckDuckGo Privacy Essentials.

Cookie AutoDelete

As the name implies, Cookie AutoDelete is responsible for automatically deleting HTTP cookies after closing the browser tab. This extension offers a high level of protection against tracking through cookies without affecting the performance of websites. In addition, Cookie AutoDelete also provides protection against traces of Flash code, ETags and cleans DOM storage.
