The Tor Browser / file revision

 # WebappRT doesn't need these instructions, and they don't necessarily work

 # with it, but it does use a GRE directory that the GRE shares with Firefox,

 # so in order to prevent the instructions from being processed for WebappRT,

 # we need to restrict them to the applications that depend on them, i.e.:

 #

 #   b2g:            {3c2e2abc-06d4-11e1-ac3b-374f68613e61}

 #   browser:        {ec8030f7-c20a-464f-9b0e-13a3a9e97384}

 #   mobile/android: {aa3c5121-dab2-40e2-81ca-7ea25febc110}

 #   mobile/xul:     {a23983c0-fd0e-11dc-95ff-0800200c9a66}

 #

 # In theory we should do this for all these instructions, but in practice it is

 # sufficient to do it for the app-startup one, and the file is simpler that way.
