Comment (by cypherpunks):

 Previously I've been able to glue the 1Password extension into TBB (not
 supported by the 1P folks, but it worked, see post
 [http://discussions.agilebits.com/discussion/comment/99714 here] and post
 linked in that post). That appears to no longer work. I'm not certain, but
 I wonder if this fix has broken the ability to do that (the 1P extension
 uses Websocket connections to 127.0.0.1 to communicate with a helper
 process, see [http://help.agilebits.com/1Password_Windows/helper-not-
 connected.html here]).
