Actually, that might be a thing of the past… the Mozilla specs are described rather well. Speaking of the past, I’d be more interested to run several late versions of Opera with the Presto engine. Of which the most recent update was this year by the way. That browser’s more of a mystery.
Edit – wow, this is invaluable. Nobody seems to really care though because I found it wading through the Opera site, Google didn’t turn up much of this.
