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 best Browser browser!!

Decent results and doesn't track you. I don't think I have to say more

Unfortunately, the add-on breaks some sites, preventing their links from working. This occurs even when the site is added to the whitelist. In order to use the broken sites, I had to restart FF with this add-on disabled. This is unacceptable behavior.

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)

The ToS Privacy data that feeds the ranking system is not maintained at all. So most sites show a B+ rating even though they are not to be trusted at all. Very misleading.

Excellent tool to track the trackers!
