Comment (by arthuredelstein):

 Replying to [comment:8 neillm]:

 > This patch has been applied to tor-browser-52.2.0esr-7.0-1-build1 and
 tested on Ubuntu 16.04.2 LTS.

 Thanks -- I built with the patch and it worked as described. But the
 `aContext` argument of `nsTransferable::Init()` appears to have only one
 purpose, which is to check for PBM state. So I wonder if you think it
 would make sense to change the signature to `nsTransferable::Init(bool
 isPrivateBrowsingMode)`? Then perhaps the callers could be modified to
 provide PBM state, assuming they have that information:

 https://dxr.mozilla.org/mozilla-
 central/search?q=%2Bcallers%3A%22nsTransferable%3A%3AInit%28nsILoadContext+%2A%29%22

 (I'm not sure if this is a practical idea or not, so feel free to
 disagree.)
