Useful extension, most useful for customising mail headers, particularly in conjunction with header scroll extension & Display Mail User Agent.
As mentioned before; attaching "Mnenhy/0.7.5.666" to the User-Agent header serves nothing and should be taken out.

This review is for a previous version of the add-on (0.7.5.666).
