Mozilla has released the new Firefox 4.0 Windows Theme Mockups. Although not final, the new Internet browser does appear very similar to Google Chrome as shown below.
VERSION A – Tabs-on-Bottom
This version adds a Bookmark widget as a replacement for the current Bookmark menu/toolbar.
VERSION B – Tabs-on-Top
This is very similar to Google Chrome with its taps on top concept and is therefore not consistent with previous Firefox browsers.
