Very useful extension! I like to use it)
Очень полезное дополнение (реализует то, что по идее можно сделать функцией по умолчанию), просмотрел исходный код, ничего подозрительного не нашел.

Does exactly what it says, and does it very well. How this isn't a built-in feature of Firefox in 2021 boggles my mind.

Great, should be a default option in Firefox.

Could be more intuitive, but it works great.

Works great! I was looking for something like this.

For whatever reason I can no longer just type in search phrases into duckuckgo.com in the main url bar with my custom settings. I simply want dark themed These options. (https://mycroftproject.com/search-engines.html?name=duckduck+dark). along with unfiltered ad free results instead of blaring white in my duckuckgo search engine. I though it would be easy to tweak back to normal. This add-on seemed promising for that purpose, but now (Friday 4-23-2021) for whatever reason its flawed for me exactly the same way reviewer Noxanne said ith a 1 out of 5 star rating (11 days before me) is. All it did was send me to the customized duckduck page colored dark but without search results (as though I typed no search phrase at all! and just typed "duckduckgo.com" ). This add-on shouldn't even be necessary, but it sounds great if it works. Its obviously broken from some Upgrade of Firefox version 80something or maybe because I have he linux version? I don't know. Good luck developers.

I tried putting in "https://images.google.com" and all it did was send me to the default Google Image page, effectively making the whole add-on pointless. Then I put in "https://images.google.com/search?q=%s" as the address for the search engine and Firefox would not even react to me pressing Tab.

On top of that, developers should refrain from using programmer jargon when developing add-ons such as these. Extensions for web browsers should never require the user to manually type in things like "addons:extensions#search". There should be a button for when the user wants to check their list of installed search engines.

Спасибо большое, не знаю, что я делал бы без этого расширения!

This should be the first thing you see when you click "Find more search engines" in the firefox preferences.
