Comment (by Thorin):

 OT, FYI: HWA=off mitigates the history leak in our PoC ( it seems
 disabling HW acceleration slows it down to a point where the attack is no
 longer really practical) - it's just a side affect, that was all. It is
 more related to https://bugzilla.mozilla.org/show_bug.cgi?id=1477773, but
 the PoC does not care about layout.css.visited_links_enabled=false. I do
 not know what the bugzilla is (if any) as I do not have access to "access
 denied" bugs - but its clearly not a TBB issue if you disable history :)
 And Tom Ritter / Mozilla are aware of it

 sorry for unloading this OT at yer! :)
