To answer your 2nd point first, yes, mint does install some plugins by default. But what I meant was are you using the same FF profile across installations or installing the same plugins? By default ubuntu doesn't install with multi-media codecs installed by default though mint does, so are you installing these after installation? Maybe there's a common factor.
