The Cutting Edge
Next-Generation Graphics
You have to see it to believe it. The rendering of text and graphics, including SVG and Canvas, is faster and sharper than ever before, thanks to our upgraded graphics engine. Firefox automatically color corrects images that have the color profile data included (like your digital photos) to make sure the colors are exactly as intended.
Web Application Integration
Expand the power of Web-based applications. In the past you’d click on an email address in a Web site and your computer’s default email application would open up to send a message to the linked address—even if you never email through the program. Now you can choose a Web mail clients (like Hotmail, Gmail or Yahoo! Mail) to launch when you click on that email address.

Security & Privacy Watch the Video

Anti-Malware
Firefox protects you from viruses, worms, trojan horses and spyware delivered over the Web. 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.

Anti-Phishing
Shop and do business safely on the Internet. Firefox gets a fresh update of web forgery sites 48 times in a day, so if you try to visit a fraudulent site that’s pretending to be a site you trust (like your bank), a browser message—big as life—will stop you.
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
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!
Parental Controls
Enforce parental control settings you’ve entered on Windows 7 — stop unwanted downloads and more.
Outdated Plug-In Detection
Some web pages require that you install small applications called plugins to watch videos, play games or view documents. These plugins are written by other companies, and it can be hard to make sure they’re always up to date. Since outdated plugins are a security risk, Firefox will let you know when you have a plugin that’s vulnerable to attack and direct you to the right site to get the updated version. View our plugin check page.
Clear Recent History
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.
Private Browsing
Sometimes it’s nice to go undercover, so turn this feature on and protect your browsing history. You can slip in and out of private browsing mode quickly, so it’s easy to go back to what you were doing before as if nothing ever happened. It’s great if you’re doing your online banking on a shared computer or checking email from an Internet café.
Customized Security Settings
Control the level of scrutiny you’d like Firefox to give a site and enter exceptions—sites that don’t need the third degree. Customize settings for passwords, cookies, loading images and installing add-ons for a fully empowered Web experience.
Add-ons
Firefox looks for a secure connection before installing or updating add-ons, 3rd party software, and Personas.
Anti-Virus Software
Firefox integrates elegantly with your Windows 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.
Super Speed
View Web pages way faster, using less of your computer’s memory.
Private Browsing
Surf the Web without leaving a trace.
Easy Customization
Thousands of add-ons give you the freedom to make Firefox your own.
