I installed it but it does nothing

Excellent!!!

Making me feel a little more comfortable surfing the web, free from spooky trackers.

so weit zwar ok, - aber wenn man es deinstalliert,
lässt sich die Startseite nicht mehr wirklich ändern - sie Springt immer wieder auf DuckDuckgo zurück.
Es lässt sich also nicht wirklich deinstallieren!

und sowas kenn ich eigentlich nur von Adware und ähnliches Zeug.

Sowas geht gar nicht!

If you're complaining about being locked out of websites you can simply turn off privacy protection.

If you are wondering why Videos can't be Loaded on websites, then this Extension is very FAULTY.
I had to Uninstall this Extension, Because it was Blocking a Live TV channel website, from my Country Cyprus:
http://www.sigmatv.com/live
It couldn't load the video to watch the channel. Other browsers was loading the video with no problem.
I discovered that it was this Addon, Because I had to go through a "Painstaking process" Disabling ALL of my addons and start Enabling them back again from the start. One-by-one, to discover which Addon was faulty.
And this addon was blocking this channel video.

Its the best add-on

easy to use, most of the time i don't even notice it's there but it still does its thing: go go duckduckgo!

Yuh,good one

Pas mal manquerais cependant un upgrade insecure request

working as of 14 Feb 2018

I hated it! The extension locked me out of my bank account that is protected by Trusteer.

When I installed this on my old box (Compaq Presario, 2GB RAM) and my Asus Netbook (Windows 10 version I bought a year ago), it slowed down Firefox so much that new tabs would not load. It swallowed 100% of my Disk access. I was about to abandon Firefox until I followed the recommendation to disable my add-ons. When I disabled this plugin, the problem disappeared.

Amazing !!!!! It should be available for android's firefox too !!!

Simpel ,einfachsnel und gut qua securty ! 5 sternen wert !. Gruss Tom.

I've become a big fan of duckduckgo over the past few years as I've grown more aware of the rampant privacy/security transgresisions that flock with you everywhere you go on the web. I like this extension - it worked well enough, but for me it felt like a bit of a compromise so that more people will use it (which I think is a really good thing in a lot of ways) compared to the mix of privacy/security extensions I usually run. That extra protection comes at the cost of lots of manual feedback/whitelisting/blacklisting to pretty much every new site I got to which is a pain in the ass, and is prone to breaking sites which means I've got to spend more time tinkering with the settings. This extension however, seemed to work well enough out of the box and hasnt created any issues with breaking sites.

If you're at all concerned about privacy, or feel violated by companies watching everything you do on the web and then selling that to whomever is willing to pay for it, but arent wanting to spend anything more than a nominal amount of time to protect yourself than this is a great option.
