Firefox 5 Mockups Reveal "Site-Specific Browsers", Updated Location Bar

While Firefox 4 is still in beta and even though it seems it will be released in March, it might actually be further delayed, the first Firefox 5 mockups are already starting to emerge.

 

It seems that Mozilla will adopt something called "site-specific" browsers (this is basically the old Prism with a new look) or "desktop apps" starting with Firefox 5, which will have an integrated site menu.
