Slows many websites to a painful crawl. Took me quite some time to pinpoint as I never thought DDG would be the culprit.
If you enjoy or need weather radar maps & such, this addon will render them almost useless...

Breaks logins on many sites. For example, Fedex.com gives me an error message when I try to log in. If I disable the DuckDuckGo extension and reload, I can log in with no problem. Too bad, because I love DuckDuckGo as a search engine. But this extension is apparently too aggressive for many websites to work properly.

I use this extension in Firefox on my home PC with no problems. However, when I try to use it on my work PC, Firefox won't load any web pages until I disable the extension - which is very frustrating. No doubt there is something different in settings which I am unaware of which is preventing the pages from opening?
The other extensions which I use, AdBlocker Ultimate & Facebook Contaner, seem to work fine on both PC's.

Je n'ai rien contre l'extension, juste contre le moteur : Premier essai, première recherche, pas foutu de comprendre les mots clés que j'ai entré "graines de niger" ne m'a sorti pour résultat que des pages "graines de nigelle" aucun autre moteur de recherche que j'ai essayé ensuite ne s'est planté, c'est le seul ! Donc je n'ai pas de temps à perdre avec ce genre d’approximation.

Mostly works fine, but does block any and all access to banking websites. Unsure whether this is solvable, perhaps banks simply use too much tracking software or maybes it's an oversight

DDG is quite good search engine, but this extension makes too much slow-downs on many sites.

This add-on will broke your Deezer.com

is not displaying some sites correctly, maybe some conflict with the ublock origin

Twice now when I've had problems with sites acting weird, (like not being able to resize or even move a window) it's turned out to be DuckDuckGo. Think I'm done with it.

BUG! This week it started blocking all connections to my bank's billpay service (netteller.com)... not sure why.

Some redirects not working properly with this extension.

Tried this for some time but search results in UK are poor.

There are two things I don't like about DDG. I can't find a way to have same interface colours I have, in Search screen, with Google and Dark Reader together. That is just more readable and comfortable for eyes. With DDG, with or without Dark Reader, I have other tints of black, blue and purple, the 3 major colours in the seach screen.
And the other thing, is the lack of a proper integration with Google services (maps, youtube, etc). When you search for an address, it doesn't immediately show Google maps screen of it, but you have to do 3-4 clicks to have that.

Conflicting with Simpletabgroup addon, causing lag and freeze. After disabling DDG, Simpletabgroup works fine again.

This extension is cool enough to use, but frankly could be a lot better. Among other things, it should ( but doesn't ):
- provide enhanced features to ddg
- add a !Bang drop-down menu
- optionally save search terms
- save filter options
- omit hits from specified domain(s)
- make ddg settings persistent across devices with extension installed 9 via ff account association or otherwise ).
( Extensively tried in Linux & Windows10 ).

But, at least it does enhance my data privacy. Viva la libre!

При использовании дополнения не отображаются тайлы встраиваемых карт Яндекс.

I will not pretend to have any idea as to how to measure privacy, and thus will not comment about that.
But I do know when my browser, core and ram are working extremely slow; My CPU and 8GB RAM are constantly maxed and Firefox stops responding for ten seconds approximately twice every minute! This happens regardless of whether there are five hundred running tabs, or only five. I wouldn't recommend using this extension until this issue is fixed.

Have used it awhile but I have become increasingly frustrated by irrelevant search results that are little more than 'where to buy' redirects.
