Although I haven't done this, I think I've seen enough to opine a little
bit...
Firefox - Even on "That other OS" to do this at the application level
you need to compile a custom version of the application, although it's
probably also possible to modify the default config file which requires
"only" a few more steps than simply editing a file... Try this article
by a MacOS Admin (which should still apply)

As for setting Firefox itself as the default web browser, at least on
my machine KDE does this automatically with FF and KDE installed, I
imagine the same should be true for other major Desktops (If yours is
different you'll likely need to specify the Desktop). Note though in KDE
that certain local HTML documents will default to Konqueror instead of
Firefox.
As for saving in default formats, I personally would not recommend
modifying because I've often seen openoffice format files display
improperly in Microsoft Office apps. Sure, the file will usually open
but I've often seen strange and missing layouts, formats, themes, more.
Still, if that's what you want to do apparently you can do a Tools >
Options > Load/Save > "Always Save As"
Instead, I strongly recommend always saving to the native, install
default and optionally saving in the non-default format <in addition> so
that you'll always have a copy of the file as it was meant to be viewed.
HTH,
Tony
