What Chrome asks you to allow

• Read and change all your data on all websites
• Read your browsing history
• Display notifications

Derived from the manifest by Chrome's documented rules; the dialog's exact wording depends on your Chrome version and language. Chrome asks again if an update requests more.

Every site you visit. This extension can read and change the content of any page you open. What access to every site means

Reaches your browsing data or every site
