Microsoft's Firefox add-on simply replaces the browser's <video> player with a Windows Media Player object, so the fees have already been paid for as part of their licence to include an H.264 decoder with all copies of Windows.
Supporting H.264 makes sense for Microsoft as a licensor of the patent pool.
My extrapolation is a reach, but supporting h264 on Firefox doesn't make sense except if MS is seeing cash from h264 ubiquity.
