I believe this will rely on bug 941063 being fixed which will not happen in the FF26 timeframe as we are about to go to release so marking this for FF27 and later.

I'll not be able to work on this before next week's merge, but probably I can get to this before the holidays. In that case we can have the fix ready for an early beta.

Maybe Neil or Felipe have some time earlier, I'll comment on bug 941063 so that the work can be taken by whoever among us becomes available.

As mentioned in bug 941063, this has been around a while and is an issue in very few download circumstances, due to that we will not consider this a release-blocking bug to track.  Low risk uplift nominations considered when a fix is available.
