Firefox is a fast, full-featured Web browser. It offers great security, privacy, and protection against viruses, spyware, malware, and it can also easily block pop-up windows. The key features that have made Firefox so popular are the simple and effective UI, browser speed and strong security capabilities.

Firefox has complete features for browsing the Internet. It is very reliable and flexible due to its implemented security features, along with customization options. 

Firefox includes pop-up blocking, tab-browsing, integrated Google search, simplified privacy controls, a streamlined browser window that shows you more of the page than any other browser and a number of additional features that work with you to help you get the most out of your time online.

Do what you do online. Firefox Browser isn’t watching.

How Firefox compares to other browsers: Get all the speed and tools with none of the invasions of privacy. Firefox Browser collects so little data about you, we don’t even require your email address to download. That’s because unlike other browsers, we have no financial stake in following you around the web.

We block the ad trackers: You explore the internet faster. Ads are distracting and make web pages load slower while their trackers watch every move you make online. The Firefox Browser blocks most trackers automatically, so there’s no need to dig into your security settings.

Firefox is for everyone:  Available in over 90 languages, and compatible with Windows, Mac and Linux machines, Firefox works no matter what you’re using or where you are. Make sure your operating system is up to date for the best experience.
