SuperSearch 作者: Janghou

Supersearch the web by searching different sites in one go.

Set it up to your taste!

TL:DR
Supersearch the web! Type 'ss web paint api' and start learning about the paint api :)

This will search in:

1. developer.mozilla.org/en-US
2. developer.chrome.com/docs/extensions
3. caniuse.com/
4. whatwg.org

For some sites it will search through a web-engine!
