Is this a joke?? It can only make a simple conversion for typed in numbers? And you can't even copy the resulted number?? How about converting all the different value currencies of a page to one common??? OMFG

Is Currency Converter Safe?

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.

Currency Converter requires very minimum permissions.
