Well, they did do a ground-up rewrite of the mosaic code for their second 
release of Internet Explorer - something that would be a vast improvement if 
Mosaic were to do the same, especially with modern considerations and 
security.

There are still bugs in Mozilla that I recognise from very early releases of 
Mosaic.
