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

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?

see title

thanks eff for this tool!

Muchas Gracias nos ayuda a comunicarnos mejor, que buena idea del desarrollador.

To all the fools here who underrate this add-on on the basis that it doesn't block some ads - you need to read the description before posting your ignorant crap in reviews. This is NOT an ad blocker, and it doesn't claim to block all kinds of ads. Stop whining that it is not something it never claimed to be in the first place.

That's like underrating a smartphone because it doesn't work well as a hammer. It's stupid and ignorant.

I would suggest to the developer to make it even more obvious that this is not meant to replace a conventional ad-blocker. Maybe put that in CAPS in the description for all the lazy users.

Great tool btw! :-)

Too many want to compare this to AdBlock, but they are very different things. This is not intended to block ads, and AdBlock is not intended to protect your privacy. This blocks cookies and/or content from being loaded from third-parties if that third party appears to be tracking you on multiple sites. That happens to have the effect of blocking some ads, but it also blocks analytics, Like/Tweet buttons, tracking pixels, etc.

Would be nice to have controls per content-type.

Privacy Badger protects you only from spying ads and invisible trackers. If you want to be protected also from all kinds of ads including an anti-adblock killer, want to use famous filter lists like EasyList, EasyPrivacy, Peter Lowe's Ad Server list, and many filters for malware protection, want cosmetic filter, an element picker for pushing away things you don't want to see anymore and to make your own filter rules, want a filter against obtrusive cookie notices, want an ad blocker with very low use of CPU and memory, than you have to take uBlock Origin

Good

Effectively blocks tracking domains and cookies. Didn't find it to interfere at all with my browsing, nor did it break any site I visited.
Being developed and updated by the EFF is a trust warranty, as opposed to other alternatives.

As it is a really non-intrusive and effective addon, I would recommend it for any firefox user, independently of their knowledge level.

Easy to manage, easy to control, and it works well for sites which break if you disable their add tracking by simply allowing the content but blocking its cookies.

This is your one-stop-shop for privacy (that and HTTPS Everywhere).

Vraiment excellent, merci à eff.org
