This plugin crippled my browsing experience. Some sites pegged my CPU at 100% with this extension enabled. A great shame because I'm a fan of their search engine, but it had to go. Browsing is now very fast again.

The only other add-on I use is uBlock Origin. If this occurred because they're incompatible, it's uBlock that wins.

Excellent addon, concept and search engine. I'll probably never stop using it. The only problem I detect with this addon is that it seems to take almost 100MB of RAM on FF 57 on Linux (I compared Firefox's memory footprint with it enabled vs. disabled). For memory-scarce computers such as mine, that's quite a lot. I hope you can improve this please. Congratulations to the DuckDuckGo team!

Good at finding sites. Like the fact that it does not track me. Needs to be updated for Firefox 57.0- it blocks BusinessInsider.com

I love the concept. Admittedly, sometimes the search results are a little lacking (ie. I'll find what I want on another engine more easily.)... still, it works well and does what it says. Thanks

Great

Best Search

Google is shit. DuckDuckGo is awesome. Thans for the Privacy

I love this extension, but I've noticed that strangely, only DuckDuckGo seems to ever get an A rating... So strange...

great knowing my data isn't going to big brother's uncle
