Engine Switcher

A WebExtension to switch current page between various search engines in just one click (or Ctrl+Alt+N), if you are too lazy to type !b, !g (especially on mobile) in DuckDuckGo.

Permission

For paranoid users such as me, these are all used permissions with its usages:

• tabs:
  • Watch the URL changing of all tabs, for checking if URL is supported stie, and decide if show / hide pageAction button. (browser.tabs.onUpdated).
  • Get the URL of current page (Tab.url in pageAction.onClicked)
  • Redirect to new URL (tabs.update({url: string}))

  Firefox for Android requires developer call browser.pageAction.show() explicitly and it’s impossible to use pageAction with only manifest.page_action.show_matches to implement this extension.

• storage:
  • For saving user preferences in your Mozilla account (storage.sync)
• startpage.com
  • startpage.com protect privacy in a extremely paranoid way: it’s impossible to get query string from URL. Therefore, I have to inserting content.js to get query string from <input>.
