Damn, it seems that fix for it will require browser update As bugging Nokia to implement it is totally hopeless, I guess we'll need a Open source browser replacement in some point of future... Using Iceweasel via Easy Debian may be workaround, but I'm not sure about it, cause never version of Iceweasel - addressing issues - may require gconf2 update. And ever if - somehow - we may force it to work, it's hardly a solution.
