Comment:

 I think it makes sense to pick up
 https://bugzilla.mozilla.org/show_bug.cgi?id=1234246.

 We could also backport these two performance fixes that went into FF46:
 * https://bugzilla.mozilla.org/show_bug.cgi?id=1233818 (8 patches!)
 * https://bugzilla.mozilla.org/show_bug.cgi?id=1235046 (non-trivial patch)
 And there is also the following fix for a somewhat rare crash which will
 appear in Firefox 48:
 * https://bugzilla.mozilla.org/show_bug.cgi?id=1238694

 gk (or anyone with an opinion): What do you think? My opinion is that we
 should skip the two performance patches but pick up the crash fix (that
 patch is fairly simple, but there is some risk because Mozilla has not
 shipped it yet).
