What Chrome asks you to allow

When you add it, Chrome asks you to allow it to:

• Read your browsing history

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.

What it can reach

No site access is declared in the manifest, so it cannot read the pages you open on its own.

• See the address and title of every tab you have open tabs

Routine for an extension
