Simple to use, minimal overhead.
Deserves 10 stars!

Have used since beguinning and works great.

This app makes it so easy to block tracking by third parties and makes it even easier to fix a page when it is broken by a filter, unlike other popular blockers.

Top!!!

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.

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

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!

Add-on, for me, largely replaces the old Ghostery add-on (which no longer blocks cookies or apparently much at all really). The traffic light system is insanely simple to understand, and makes it quick and easy to fine-tune your experience. It would be great if you could combine a filterlist with it so you have instant, out of the box protection without having to install an ad-blocker. It would also be great if it provided some indicator on why it considers a url to be tracking you- a hit count for each attempted access, for example, or even just make the title text for each site a darker font (and vice versa).

Also, I know they have done it for a while now, but I respect EFF for finally producing their Add-Ons on the official Firefox repository... Although they probably didn't have a choice with it impossible to install unsigned add ons now on anything but the Developer version of the browser. I feel this is what EFF should have done all along, to counter clones appearing instead, along with maybe a warning about Firefox's policies. Although I'm in support of the reasons EFF declined to upload add-ons like https Everywhere for such a long time, for me the ultimate aim of getting the protection offered to as many users as possible probably should have been the more important focus?
