Perhaps if we found some creative commons icons to use as defaults for the
most used extensions. It wouldn't match the native theme but at least we'd
have something for cases where platform icons are not available. We'd need
to have some number of sizes. I think Windows goes to a max of 72x72, while
Mac OSX goes to 128x128. Mozilla defines the size as:

   *   Parameter:   size   *   Values:      [<integer> | button |
toolbar | toolbarsmall | menu | dialog]   *   Description: If integer,
this is the desired size in square pixels of the icon   *
  Else, use the OS default for the specified keyword context.


<integer> scales the icons to the desired size. I think we'd at least
need a few different sizes for a default set of icons. I'm not sure
that such icons exist.
