It does what it says to do so, but it has a poor configuration interface, I didn't know where to look at first.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

AddHeader requires a few sensitive permissions. Exercise caution before installing.
