# bookmark-it ## What it does Displays a simple button in the menu bar that toggles a bookmark for the currently active tab. To display the button, the extension registers a [browserAction](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/browserAction) in the manifest. A background script will listen for tab events and update the browserAction icon correspondingly. It also listens for `browserAction.onClicked` events to create or remove a bookmark when the user has clicked the icon. ## What it shows * how to use the various `bookmarks` functions * create a bookmark * remove a bookmark * search bookmarks by url * how to register a browserAction * how to listen for tab changes
