Mozilla just launched Firefox 149. This version comes with exciting new features, particularly a built-in VPN. Users now get 50GB of monthly data to help them stay private online.
The VPN works by using a secure proxy server, but it only protects traffic from the browser itself. This is different from the regular Mozilla VPN, which secures all internet traffic on your device.
According to Mozilla, “Whether you’re on public Wi-Fi, searching for sensitive info, or shopping for personal items, this makes it simple to stay safe.” Turning the VPN on is easy—just sign in and switch it on to hide your location and IP address while browsing.
Users will be notified when they’re close to reaching their limit. The VPN can also be set to activate only on specific websites, making it handy for those who want to save their data.
It’s important to note that some essential websites are not routed through the VPN to prevent login issues. Mozilla claims they only collect data necessary for improving service performance. They might log connection successes or failures and how much data is used each day.
The VPN’s server is based in the U.S., carefully chosen for optimal speed and user experience. Currently, the feature is rolling out in the U.S., UK, Germany, and France, with plans for further expansion later.
Firefox 149 also includes a new Split View feature. This function allows you to view multiple tabs side by side, which can be great for tasks like planning or comparing information. It’s similar to a feature already offered by Google Chrome.
Additionally, Firefox will now block notifications from sites flagged as malicious by the ‘SafeBrowsing’ security system, enhancing user safety even further.
Security is a major focus in this update too. Firefox 149 fixes over 46 vulnerabilities, some of which are quite serious. This includes issues with user-after-free errors and flaws in the JIT engine that could let attackers bypass protections.
The landscape of online threats is evolving. According to the Red Report 2026, many new malware techniques now use advanced algorithms to detect and evade traditional security measures. Staying informed is more critical than ever.
With all these updates, Mozilla aims to enrich user experience while prioritizing security and privacy. For a deeper dive into internet safety trends, check out reliable resources from the Cybersecurity & Infrastructure Security Agency.
