Update easier would be nice Rated 4 out of 5 stars

Fairly weak because it isn't updated. You would think it would be easier to update user agents that are available. Copy and paste will work, but this could be done simpler and automated, so it is less of a hassle. Still, probably the best extension of its kind for mozilla browseer. Why aren't there more extensions for User Agents!! This is valuable for proxy and internet tethering.
