PB is a great way to reduce tracking across the web. It uses heuristics to determine if a tracker is doing something it shouldn't, and blocks them accordingly. It does catch some trackers that add-ons with static lists sometimes miss.

easy and safe

Privacy Badger is in combination with pi-hole and HTTPS Everywhere the ideal privacy tool.
Now if the data could be synced with Firefox Sync it would get the much deserved 5 stars.

Great!

To not be tracked from site to site is great and PB does this without any fuss or muss. 10/10. Easy to use and install. Love EFF Tech.

Great add-on

gran aplicación

I have a Pi-hole attached to my router which blocks a lot of ad-serving sites, trackers and malware sites.
I thought I had things covered pretty good, but when I started using Privacy Badger it still finds some trackers to block.

Great job EFF, thank you!

Now my only wish is that you make this available for MS Edge. I still prefer the lean-and-clean minimalistic approach of Edge over Firefox, but for privacy reasons (cookies management and Privacy Badger) I moved to Firefox.

Works great in Chrome not, so great but good in Firefox. Does not slow down my browser at all. I think it also blocks some pop-up ads, but not all. Too bad MSN is not jumping on the bad wagon..

How does Privacy Badger interact with things like uBlock Origin & Ghostery?
Do their functions collide with Privacy Badger (PB), like they block something before PB can analyze it?

This addon is very disappointing. I cannot give the reason why in this space because my reviews have already been deleted twice by the moderators. Just benchmark the addon for your Internet uses with uBO-Scope and see what is not blocked despite training Privacy Badger for weeks.

Edit: I update the score to positive, because the Google Analytics issue is fixed:

The great difference between Privacy badger and other blockers is that it learns what follows me on the internet and blocks it on every website.

Love it

Excellent! Use this and adblock on my laptop and it works very well!

First, I would like to thank EFF for this add-on.

The GUI would need some work, it looks 1995.

it doesn't block "everything" I prefer to block all Google stuff that I cannot block in my router but this doesn't block youtube ads and ads spies on you ;) (i know this is for privacy but ads on youtube makes so many ajax calls its ridiculous - and we know Google love knowing everything)

4/5 I would recommend but need another extension to fully satisfy my intense browsing

Maybe add a opt-out feature for ads that tracks us
