I would not recommend this plugin. The uninstall does not work. Be warned that it does not remove preferences and does not set the preferences back to what they were before installing it. For those of you wanting to uninstall and get external links working again you need to set the following:

network.protocol-handler.external-default
and it's set to true.

This review is for a previous version of the add-on (3.2.8.1). 

I've yet to experience the uninstaller not working. Did you choose to delete all ThunderBrowse preferences?
