A couple of simple questions about mozilla (I'm running version 1.4 at the moment):-
Is there a list of the 'about:*' things that you can enter as URLs anywhere? They are incredibly useful but I can't remember them. The only one I can remember is "about:plugins"
Sort of follows on, where/how does mozilla decide what file type suffixes it recognises? My mozilla at work recognises .jfif files but my copy at home doesn't.
I've searched Google for the above and I've looked at www.mozilla.org but haven't had much joy.
