CloseReview for User Agent Changer by avada
Rated 4 out of 5 stars
This would be really could if the addon could browse useragentstring.com, to load UA strings from there. Because that site has up to date user agent strings.
Or an autoload a constantly updated xml list would be about as good too. But I don't know of any such lists...
