"Access your data for all websites"? no thanks

What is access your data for all websites?

The extension can read the content of any web page you visit as well as data you enter into those web pages, such as usernames and passwords.

Extensions requesting this permission might:

Offer a password manager that reads and writes details of your username and password
Provide an ad blocker by reading the content of each web page you open to find and remove ad code
