Comment(by mikeperry):

 Ok, I got some info from #mobile on irc.mozilla.org. mfinkle said that we
 should definitely only register the http-* observers in the parent
 process, as those are fired for every element load.

 fabrice said that AdBlockPlus registers a content policy for each child
 process and implements a cache to avoid performing the message passing RTT
 for every element:
 https://hg.adblockplus.org/adblockplus/file/7d47f4083064/modules/ContentPolicyRemote.jsm
 https://hg.adblockplus.org/adblockplus/file/7d47f4083064/modules/Utils.jsm
 https://hg.adblockplus.org/adblockplus/file/7d47f4083064/chrome/content/fennecContent.js

 He did not know why ABP still registers http-on-modify-request as well as
 onChannelRedirect in the remote children. It has something to do with
 properly tracking channels according to the comments. Not sure if it is
 required because onChannelRedirect is not fired to children, or if it is
 merely a scoping convenience thing..

 Sounds like a real proper mess that the ABP people managed to untangle
 enough for it to function, but it still doesn't sound very sane, robust,
 or efficient...
