# notify-link-clicks-i18n **This add-on injects JavaScript into web pages. The `addons.mozilla.org` domain disallows this operation, so this add-on will not work properly when it's run on pages in the `addons.mozilla.org` domain.** ## What it does This extension includes: * a content script, "content-script.js", that is injected into all pages * a background script, "background-script.js" The content script listens for clicks in the page it's attached to. If a click is on a link, the content script sends the link's href to the background script. The background script listens for this message. When the background script receives the message, it displays a notification containing the href. The notification's content, as well as the extension's name and description, are localized into German, Dutch, and Japanese, as well as the default en-US. # What it shows * how to inject content scripts declaratively using manifest.json * how to send messages from a content script to a background script * how to display system notifications using the notifications API * how to use the internationalization (i18n) system
