Great, I use it to set duckduckgo as my default search enginee. It only lacks the feature to set duckduckgo lite as the search engine. It's considerable faster in my region and it firefox dont sync search engines so i have to configure it all the time. (if you guys do so please also add per user config cloud saving plz).

thank you duckduckgo team for your service. FFFFFFFF

Even though some websites do not work correctly after activating this extension, I like the features it gives me to protect from all the various trackers found on the web.

DuckDuckGo has the important benefit of not tracking you. Sadly, it isn't perfect in terms of search relevance sometimes. But this is understandable, Google has had an obscene amount of time and tinkering to get to where it is today. DuckDuckGo can do the same, given enough time.

The privacy rating could really do with more information as on the vast majority of websites there are many "unknowns" even for the big websites.Seems to have no effect on YouTube or Google.Otherwise helps with privacy on some websites & works on Firefox Quantum (Linux)

Generally great but it did prevent me from signing up to a newsletter on https://pegasys.tech/. I had to selectively disable all my add-ons to work out which one was at fault.
