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.)
