that fix was working for me since i upgraded to firefox 3.5

but since the update of nvidia driver recently and firefox update too.
this fix does not work ANYMORE.

look at https://bugzilla.mozilla.org/show_bug.cgi?id=496831
and other duplicated bug reports

it is supposed to be fixed. so it's coming in some near future
