Rated 4 out of 5 stars

Works well. I used it for an online job application that insisted on checking browser/OS. Would be handy if there were a way of specifying URL-specific user agents. E.g. if you want the website http://jobapplication.somecomany.com,
Firefox could switch to that particular user agent just for that site. Would that be possible?

This review is for a previous version of the add-on (0.6.11).
