Chrome extension permissions

Permissions stats image

Chrome extensions are powerful because they have additional permissions to perform operations that a regular website cannot. However, some permission requests may look suspicious. Watch out for extensions that requires permissions that are irrelevant to the core purpose of the extension - e.g., while an ad-blocker will likely need access to all websites, a simple new tab extension should not (unless it has a very good explanation on what it is using that permission for!)
