It's irritating that we can't pull this preference directly from somewhere,
since this is user-configurable, and also we'll have to update this for
presumably every future version of Firefox (formerly all Gecko browsers were the

Sorry to say, but r17136 didn't work :-( Firefox 2 shows still <alt-x>.

Maybe an extract of the access log of my private website may help:
