EDIT: seems that this extension need to be updated, sorry...
But I don't know, if you allow javascript maybe you will leak your real user agent?
I like to switch between iceweasel and seamonkey, and I'm "proud" of my different and unique user agent :)
Speaking of privacy, actually I'm more concerned about referer, third-party sites, content delivery networks and so on.
