What it lets an extension do
Every site you visit. This extension can read and change the content of any page you open.
Reaches your browsing data or every site
Permissions in this group reach your browsing data or every site. Plenty of honest extensions need one; check that what the extension is for explains it.
What Chrome says when you add one
When you add an extension that declares it, Chrome asks you to allow it to:
- Read and change all your data on all websites
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.
