All of the thousands of search engines from DuckDuckGo, in chrome! Simply type "!", press tab, then search for anything anywhere!
DuckDuckGo has a feature called bangs, which allow you to search any site through the following syntax:
![site] [search query]
Each site has one or more keys, for example, YouTube is "yt", and Google Images is "gi". This extension brings all of that to chrome, allowing you to search any website with ease.
