Tracking protection, private browsing and powerful privacy extensions all work together to make sure your private browsing information stays yours. With each new release we give you more ways to control who sees and accesses your personal browsing data.
With each version we make improvements to the code that makes Firefox quick and nimble as you browse. We work tirelessly to make sure Firefox is the fastest it can be, while making sure it doesn’t hog your memory or system resources. Firefox engineers have been known to ship a security update within a day of learning of a vulnerability.
Older versions of browsers may be vulnerable to attacks and security holes. Up-to-date browsers protect you from viruses, security breaches and hacks.
