As admin it works fine for both, *.html and *.htm files, but in the User account only *.html files are properly connected to FF and it seems I cannot change the *.htm association from IE to FF.
Firefox doesn't even show in the right-clickers program list and when I try to use "Open With/Choose Prg ... and select firefox.exe manually from the DIR, *.htm files are still opened with IE.

And, yes, FF is my Default browser and IE definately not.
I already did a google search, but can't find anything useful.
Help anyone?
