activeTab Permission

The activeTab permission is a specific permission used in manifest.json for Chrome Extensions^[600-developer__frontend__google__chrome-plugin-develop.md]. It grants the extension temporary access to the currently active tab when the user invokes the extension, typically by clicking its icon in the browser toolbar^[600-developer__frontend__google__chrome-plugin-develop.md].

Purpose

This permission allows an extension to interact with the content of the page the user is currently viewing. It is commonly used to perform actions on the current page, such as filling out forms or modifying the page's Document Object Model (DOM), without requiring permanent access to all websites^[600-developer__frontend__google__chrome-plugin-develop.md].

Functionality

When the activeTab permission is included in the manifest, the extension gains the ability to execute scripts or access the tab's properties in response to a user action^[600-developer__frontend__google__chrome-plugin-develop.md]. For example, an extension can use this permission to run a content script that manipulates form fields—such as automatically inputting usernames and passwords—on the specific page the user is looking at^[600-developer__frontend__google__chrome-plugin-develop.md].
