What are your favorite privacy-based browser extensions?

Question

I'm looking for browser extensions that protect user data, web behavior, etc.

Accepted Answer

They offer 3 extensions: Chrome, Firefox and Opera that encrypt your browser traffic, unblock geoblocked content,  and mask your IP address to keep your online activity anonymous. They are lightweight and won’t slow your computer down.

Used to use Ghostery, but was a bit put-off by disclosures that demonstrated a less-than-transparent approach to privacy protection. Switched to Disconnect, snagged a lifetime deal on premium, and have been mostly pleased since.

I've been recommending Ghostery for while now for users that are looking for a browser extension to help with privacy.

blocks banner ads, pop-up ads, rollover ads, and more. It stops you from visiting known malware-hosting domains, and also disables third-party tracking cookies and scripts. Plus, there are a ton of things you can do with it beyond just blocking ads.

Has a great browser extension, and ability to upgrade to their paid apps to be protected even when you are on your phone or from other programs outside your browser, who are tracking you. Have been using their app on my mac since August, and it's blocked 75.000 request so far...

I recommend privacy badger from EFF, it blocks all 3rd party trackers on page. Also, if you feel something wrong with the page you are browsing ie. video isn't loading, ui is simple and easy to permanently fix false flags.

Scary. Awesome.

Taylor Banks · Answer

Great tech from @rickdeaconx that complements other browser privacy extensions by further protecting you from attacks and letting you know about site privacy issues.

Taylor Banks · Answer

Arguably more of a security extension than a "privacy extension," but I would put forth that using strong (and potentially unknown) passwords stored securely in a zero-knowledge vault with a strong master password is one of the best ways one can protect their own privacy, so I'm dropping this here anyway. :)

Several novel approaches to enable simple, private and secure communications.

Peter Mello · Answer

After 20 years of Byzantine methods for using PGP to secure your communications, finally someone figured out how to make it painless. Somehow they manage to get you following infosec best practices without it being a chore. The free encrypted storage and file sharing kicks ass, and the teams feature lets you communicate with one or many people under a Get Smart "Cone of Silence"

Kevin Ferret · Answer

Same here, super easy to use, super clear & clean in their terms and privacy settings, very extensive capabilities.

Martin Posta · Answer

One of the best adblockers out there, fully customizable...

Peter Mello · Answer

Browsers are bad enough memory hogs as it is, so it was great to finally ditch needing an ad blocking extension in every browser. One license and my PC and Android phone are protected before I ever open a browser, and the ease of whitelisting single page elements instead of whole domains is remarkably simple and superior to the rest of the herd.
