I've installed it, found I don't need it, and that it seems to slow Thunderbird boot-up times considerably.

It would be helpful to know how to uninstall this add-on. (Win XP, sp3; Thunderbird 3.0.4)

Esta valoración es de una versión anterior del complemento (1.0.1). 

Enigmail is uninstalled like any other add-on in Thunderbird: go to the menu Tools > Add-ons; click on the entry for Enigmail and select the button "Uninstall".
