Ghostery is one of the best privacy-focused extensions with an intuitive user interface. What’s most interesting is, it uses an artificial intelligence engine to smartly block trackers and advertisements to help avoid issues on websites.

Enhanced anti-tracking of Ghostery

Ghostery offers Smart Blocking — a feature to optimize the performance of the webpages. Moreover, it maintains the page quality by intelligently blocking and unblocking non-secure or slow trackers, anonymizing your web history.

Ghostery shows just the required content and blocks everything else including online ads, thus decluttering the web pages. Also, it prevents trackers from gathering your information like your location, computer type, window size, browser, and your browsing habits, helping you browse the web safely!

Blur — previously known as DoNotTrackMe — is a perfect browser extension for securing your data and online privacy. It limits the information you share with third-parties such as advertising companies and trackers, like Ghostery.

Blurs helps to mask your email address

Blur can mask email addresses to protect your online identities. What’s most interesting is, you can also mask credit cards and phone numbers (a premium feature, sadly), protecting you from online fraud and identity thefts.

Unlike Ghostery, Blur is also one of the best password managers, helping you to manage passwords. It can encrypt, save, and organize all your passwords to help you log in quickly and securely on the web as well as on iPhone and iPad.

Private Bookmarks

Private Bookmarks adds a missing feature to Mozilla Firefox. It enables a special password-protected bookmark folder that’s encrypted with your password. The private bookmark folder can be backed up, imported, and exported too.

You can hide web pages in this private folder from prying eyes. It encrypts the folder and hides it on your machine, making it invisible. One can only access it with your password.

Settings of Private Bookmarks in Firefox

Interestingly, Private Bookmarks can auto-lock your private bookmarks when you’re idle or not using a private browsing session. Also, it can auto-lock the private folder if you close the browser while the folder was left unlocked.

Multi-Account Containers

If you’d like to organize your online life and maintain privacy, Multi-Account Containers is a great solution. It helps create containers — an isolated group of your online identities and services.

In short, it allows running two identities side-by-side, say your official and personal accounts at the same time.

Hence, you can stay logged into multiple accounts without using multiple browsers or constantly signing in and out of your accounts. What’s more interesting is, it helps isolate your accounts. So, if you search for “developer jobs” using your personal account, your work account services can’t track it.

Cookie Manager

Cookie Manager helps you to manage the cookies on any web page. It works in private mode and runs on Firefox Mobile as well. You can view all cookies, search cookies using a domain, path, or content.

Moreover, you can do a sort of actions on the cookies — add, edit, remove, whitelist, and import or export the cookies.

Cookie Manager for Mozilla Firefox

Cookies are text files that keep track of your online activities as well as your identities. So, Cookie Manager helps you to manage or remove cookies, allowing you to control web tracking.

It also recognizes cookies from default or private browsing sessions and container tabs and groups them into relevant jars.

That’s all about the privacy-focused add-ons for Mozilla Firefox. I suggest you get Ghostery — it blocks tracking-related technologies, hardening your online privacy. I also suggest installing Multi-Account Containers — an awesome add-on for ensuring isolation between multiple accounts of service (say Gmail).
