针对中国用户的重要信息：
根据中国法律，此插件中推广的服务大多是非法的，您不应该使用此插件。 因此，由于法律原因，我无法为中国用户提供任何支持，包括但不限于添加受中国政府管辖的服务（以避免鼓励中国用户使用非法的外国服务而不是合法的服务）。Important Information for the users from China:
The services promoted in this this addon are mostly illegal according the law in China, you should not use this addon. Therefore I am unable to provide any support for Chinese users due to legal reasons, including but not limited to add the services subjected to China Government (to avoid encouraging Chinese user to use illegal foreign services instead of legal one).
---------------------------------
A WebExtension to switch search engine in just one click (or Ctrl+Alt+N), for those who concern privacy but are too lazy to type !b, !g (especially on mobile with the damning screen keyboard) in DuckDuckGo. So you can easily keep your privacy as possible as you can.

This is a 100% safe & clean FLOSS. Source code and more information is at GitHub.

⚠️⚠️⚠️ If you have any problem or issue, please open an issue on Github or send me an email, BECAUSE too many people complain on Mozilla Addons and never react to my later reply as if I deserve this or I should do anything for other for free.✉️✉️✉️

About Permissions
I don't want to ask for too many permissions, but I only ask for those who are verily, indeedly required.tabs: To access tab's URL.duckduckgo.com, ecosia.org....etc.: For adding floating buttons on pages, inserting content_scripts into these domains are required. (Besides, startpage.com send search query strings via POST instead of GET, which cannot be extracted from URL, so it's necessary to be retrieved from DOM, that is to say, content_scripts.)
