Update your Software!

Updating to the latest security software, browser, and operating system provides an important defense against viruses, malware, and other online threats.

You could drive around with old, burned-out brake lights on your car, but it makes driving more dangerous than it should be. And if we all did that, it would get really dangerous, fast! Letting your systems get out of date can encourage malicious actors online, which makes everyone vulnerable in the end.

Mozilla cares about your privacy and security everywhere, not just on Firefox, because the safer the Internet is, the easier it is to create and keep it open. So please take a minute to update your software. The Web will thank you.
