Mozilla has released the latest version of their Firefox internet browser: Firefox 13. Aside from the usual bugfixes, they've added a most-visited page that pops up when you open a new tab, like Google Chrome.SPDY, which is a sort of successor to HTTP that makes browsing more secure and faster, is now enabled by default.

The new most-visited tab page, pictured above, is the biggest new feature. SPDY, as I mentioned before, is now support by default in Firefox 13, which will make browsing websites like Google and Twitter faster and more secure.

  • Restored background tabs are not loaded by default for faster startup
  • Smooth scrolling is now enabled by default
