UITour library API

This is the web API provided by the library UITour-lib.js for use by web content with appropriate permissions.

class Mozilla.UITour()

Library that exposes an event-based Web API for communicating with the desktop browser chrome. It can be used for tasks such as opening menu panels and highlighting the position of buttons in the toolbar.

For security/privacy reasons Mozilla.UITour will only work on a list of allowed secure origins. The list of allowed origins can be found in https://searchfox.org/mozilla-central/source/browser/app/permissions.

Mozilla.UITour.addNavBarWidget('forget', function () {
  console.log('forget button added to toolbar');
static Mozilla.UITour.closeTab()

The last tab in the current window will never be closed, in which case this call will have no effect. The calling code is expected to take an action after a small timeout in order to handle this case, for example by displaying a goodbye message or a button to restart the tour.

  • accountStateOK (boolean) – Whether the FxA account state is OK. If false, it probably means the account is unverified or the user has changed their password on another device and needs to update it here. In that case many other properties will not exist.

  • browserServices (Mozilla.UITour.Configuration.BrowserServices) – Information about account services attached to this browser, and with special support implemented by this browser. You should not expect every accountService connected in this browser to get a special entry here. Indeed, what services, and in what circumstances they may appear here in the future is largely TBD.

static Mozilla.UITour.Configuration.FxAConnections()

  • numOtherDevices (number) – Number of devices connected to this account, not counting this device.

  • accountServices (Mozilla.UITour.Configuration.AccountServices) – Information about services attached to this account. These services may be enabled on devices or applications external to this browser and should not be confused with devices. For example, if the user has enabled Monitor or Lockwise on one or more devices - including on this device - that service will have a single entry here.
