How to check your own extensions

  1. Type chrome://extensions in the address bar and find the extension in the list.
  2. Open its details. The Permissions section lists what Chrome granted it, in Chrome's own words.
  3. Open its details. The site access setting shows where it can run; set it to run only on click and it reaches a page only after you press its icon.
  4. To uninstall it, choose Remove on the same page.
