Creates a new tab.

This is an asynchronous function that returns a Promise.


var creating = browser.tabs.create(
  createProperties   // object


object. Properties to give the new tab.
boolean. Whether the tab should become the active tab in the window. Does not affect whether the window is focused (see windows.update). Defaults to true.
integer. The position the tab should take in the window. The provided value will be clamped to between zero and the number of tabs in the window.
integer. The ID of the tab that opened this tab. If specified, the opener tab must be in the same window as the newly created tab.
boolean. Whether the tab should be pinned. Defaults to false.
boolean. Whether the tab should become the selected tab in the window. Defaults to true.
This property is deprecated, and is not supported in Firefox. Use active instead.
string. The URL to navigate the tab to initially. Fully-qualified URLs must include a scheme (i.e. '', not ''). Relative URLs will be relative to the current page within the extension. Defaults to the New Tab Page.
For security reasons, in Firefox, this may not be a privileged URL. So passing any of the following URLs will fail:
  • chrome: URLs
  • javascript: URLs
  • data: URLs
  • privileged about: URLs (for example, about:config, about:addons, about:debugging) . Non-privileged URLs (e.g., about:blank) are allowed.
integer. The window to create the new tab in. Defaults to the current window.

Return value

A Promise that will be fulfilled with a tabs.Tab object containing details about the created tab. If the tab could not be created (for example, because url used a privileged scheme) the promise will be rejected with an error message.
