Chrome extension should ask for the necessary permissions only

[pzahemszky]

When I click "Add to Chrome" in the Chrome Web Store, I get the following request for permissions:

Add "Carbon Footprint for Google Maps™ and Others"?

It can:
Access the page debugger backend
Read and change all your data on the websites that you visit
Display notifications
Detect your physical location

My understanding is that the extension really only needs to access some of the websites, not all of them. I know that the access can be restricted in the extension settings of the user's browser, but it would be better if only the necessary permissions were asked for in the first place.
