I wonder why themes which are basically skinning elements break with new FF versions ... anyone knowledgeable around who can throw some light ?

Because...

That's because themes are a bundle of CSS style-sheets mostly and every time they change them they break the theme. They change them to adjust for changes in the interface or fix bugs. It's not a bad thing but it takes a lot of time and work to follow them.
