chrome.tabs

  • Description

    Use the chrome.tabs API to interact with the browser's tab system. You can use this API to create, modify, and rearrange tabs in the browser.

Manifest #

You can use most chrome.tabs methods and events without declaring any permissions in the extension's manifest file. However, if you require access to the url, pendingUrl, title, or favIconUrl properties of tabs.Tab, you must declare the "tabs" permission in the manifest, as shown below:

{
"name": "My extension",
...
"permissions": [
"tabs"
],
...
}

Examples #

Two tabs in a window

You can find simple examples of manipulating tabs with the chrome.tabs API in the examples/api/tabs directory. For other examples and for help in viewing the source code, see Samples.

    boolean

    Whether the tab is muted (prevented from playing sound). The tab may be muted even if it has not played or is not currently playing sound. Equivalent to whether the 'muted' audio indicator is showing.

  • reason

    The reason the tab was muted or unmuted. Not set if the tab's mute state has never been changed.
