Comment (by cypherpunks):

 > In this way it is quite easy to setup a MitM attack and remove revoked
 certificates from the blocklist.xml

 Can you to add new IDs to blocklist.xml to disable exist extensions, this
 way to make DoS against users? Will Tor Browser obey blocklist for
 TorButton and TorLauncher case too?
