Whenever you are browsing the internet, many websites you visit track your browsing habits. Companies like Google, Yahoo, Microsoft, and several others want to know everything you do in your browser.

There is no evil intention behind this tracking, they just need your data as its useful for serving ads that might cater to your interests, and they would use your data if you give it to them. But if you would rather keep your data to yourself, these Firefox Add-ons can help you.

Best Firefox Privacy Add-ons:

Many privacy-conscious users select a specific browser if it provides adequate privacy features. Although Firefox is quite secure, you can extend its privacy features by adding specific Firefox Addons you need. Since every user’s needs are different, we have listed some of the most popular Privacy add-ons for Firefox below.

1) Ad Hacker – Ad Hacker shows you which advertisers are Tracking you

Advertisers and publishers want to know more about you, so they track your Internet browsing with web bugs, beacons, and cookies hidden in your web pages.

This add-on lets you see who is following you around and how they are doing it. For each tracker, there is a description of who they are, what they do, and potential risks to you. A simple way to see what essential information gets sent back to the watchers.

Better Privacy serves to protect against not deletable, longterm cookies, a new generation of ‘Super-Cookie’, which silently conquered the internet. This new cookie generation offers unlimited user tracking to industry and market research. Concerning privacy Flash- and DOM Storage objects are most critical.

Cookie Culler is listed under Tools in Firefox. Blocking the wrong cookies can render some sites useless, so choose sites to block carefully. However, previously blocked cookies can be unblocked so it’s not a major concern.

When you send some text (e.g. an email, a web document file) to the internet, it will travel through multiple servers. Each of the servers may keep one copy of your text and most ISP’s make a nightly backup so there will be multiple copies of your text is stored. Even after you delete your text, file or email later, your text may still be somewhere you never know, for a while or for a very long time.

Lock The Text - © TechNorms

As shown above, you can select any text from any webpage and encrypt it with Lock The Text. Only people who know the passphrase can unlock it and view it.

This is a must-have addon if you are writing a top-secret novel you don’t want anyone to read. Just kidding – this is useful for anyone who values privacy over everything else.

It works with all web-based email providers like Gmail, Yahoo mail and Hotmail. So even if the account gets hacked, no one can read the emails. Pretty neat, eh!?

  • I also saw that the MyPersonalBrowser.com (http://www.mypersonalbrowser.com) website uses Firefox to create a new browser off of the computer you’re working on for private browsing on public computers. Using this service in addition to the tips above would be a strong combination. Of course it looks like the site is a “pay for” site as well.

    • Interesting concept really. Very intuitive – a browser within a browser.
      Although I understand that the server costs for such a project would be high – I think only the most privacy conscious users would go for the paid version.
      Maybe they could give a free trial for the service with ads to generate revenue somehow; making it easier for users to try it out and make a final decision…

      Well anyway, Thank you for this suggestion Bill. We appreciate it. Also, thank you for subscribing – I hope you stay with our blog for a long time to come. Keep visiting….

  • This is great information. I already have the Redirect Cleaner.

    However, I want an add-on that blocks that stupid Share thing that is hanging over this webpage now. Where it says Share with the Facebook icon, Stumble Upon Submit, and 1 tweet with option to retweet. I hate those things.

    You should take that off immediately. It’s even getting in the way of my typing this comment.

    Also, a good site to whitelist is the WebArchive Wayback Machine website. Redirect Cleaner will clean up those links too, and in that case, you want the archived links, because the original link was broken or dead. fyi.

    Thanks for the great information. We hope you post an extension to block that Share thing.

    • Hello Donna,

      You’re feedback is important and helps us know what we might be doing wrong. So we have removed the Floating “Share” bar like you suggested. Hope its better now.
      I will also look for an extension that might help remove it from any site you want.
      Glad you liked the post. Thanks for dropping by.
