Nice to have but not Outlook-compatible Rated 3 out of 5 stars

This is nice bit of feature to have, especially it lets users open MHT files in their Firefox instances and benefit from the added security that Firefox add-ons provide.

However, it is not compatible with Outlook 2013. The MHT file that Outlook generates with its "View in Browser" command does not render well in Firefox with this add-on.

This review is for a previous version of the add-on (3.0.0.1-signed).
