Ever wondered what all NEW Firefox offers You

See what’s new, what’s been improved and what’s just as awesome as ever. This is all you are having to read in this post.

Lets begin with the features I liked the most

Security & Privacy

Instant Web Site ID
Want to be extra sure about a site’s legitimacy before you make a purchase? Click on a site favicon for an instant identity overview. Another click digs deeper: how many times have you visited? Are your passwords saved? Check up on suspicious sites, avoid Web forgeries and make sure a site is what it claims to be.

Forget This Site *new*
Having second thoughts about having visited a certain Web site? With this feature, you can remove every trace of that site from your browser—no questions asked!

Anti-Malware *improved*
Firefox protects you from viruses, worms, trojan horses and spyware. If you accidentally access an attack site, it will warn you away from the site and tell you why it isn’t safe to use. Firefox checks every part of a Web page before loading it to make sure nothing harmful is sneaking in the back door.

Clear Recent History *improved*
Clear all your private data or just your activity over the past few hours with a few quick clicks. You have full control over what to delete, and then your info is gone for good—on your own computer or the one at your local library. It’s that easy.

Anti-Virus Software
Firefox integrates elegantly with your antivirus software. When you download a file, your computer’s antivirus program automatically checks it to protect you against viruses and other malware, which could otherwise attack your computer.

Private Browsing
new Sometimes it’s nice to go undercover. When this feature is enabled, you won’t leave a single browsing fingerprint behind for others to discover. You can slip in and out of private browsing mode quickly, so it’s easy to return to what you were doing before as if nothing ever happened (you can also browse privately all the time).
