Comment 103 for bug 164526

What about comment #100 is unclear? The fix is on the trunk and relies heavily on other changes which were made on the trunk as well in order to work. Backporting it to Fx2 isn't going to happen because it would require way too much developer energy and be extremely regression prone. Plain and simple, it's not worth the resources when Fx3 is already nearing its first beta release.

I know you guys aren't happy with the situation, but that's the way it is. The fix is in what will eventually become Fx3.

In the future, please follow the etiquette guidelines before deciding to spam bugs with yet another "me too" comment and forcing everybody who's CCed to it to read your thoughts on the matter. I assure you that most of us on the CC list really don't want to hear them.
