(18:06:47) GeKo: intrigeri: it's the best we have so far, but not tested.
(18:07:01) GeKo: and i don't see any sign of mozilla needing an additional fix
(18:07:23) GeKo: i'll look closer after i am getting back from dinner
(18:07:30) intrigeri: GeKo: thank you :)
(18:07:55) GeKo: (so, to answer your question: yes, i think it is worth it)
