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

• Read and change all your data on all websites
• Manage your downloads
• Communicate with cooperating native applications

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.

Has it asked for more over time?
