It's known that IET NG doesn't import dbx files from OE, but it's news to me that the import wizard in TB 52 imports them in the absence of OE. That option is not mentioned in the mozillazine article - which is odd, because many users would have been switching from OE to TB when Windows XP reached its end of life.
