Mozilla released Firefox 149 with added privacy protection through a built-in VPN tool offering up to 50GB of monthly traffic.
The feature uses a secure proxy server to route only traffic from the browser, unlike the company's commercial Mozilla VPN, which covers system-wide traffic.
“Whether you’re using public Wi-Fi while traveling, searching for sensitive health information, or shopping for something personal, this feature gives you a simple way to stay protected,” Mozilla says.
“Once you sign in and turn it on, you can hide your location and IP address by routing it through a secure proxy while you browse in Firefox.”

Users with a Mozilla account will get 50 GB of traffic per month. In-browser notifications will alert them when they approach the limit.
You can turn on the VPN feature through a toggle switch in the top right of the browser interface. There is also the option to activate the VPN only on specific websites, up to five, to save traffic.
Some websites and essential services are excluded from VPN routing to avoid account sign-in problems and make sure VPN reconnection works properly.
Mozilla says that it will only collect technical data relevant for maintaining the performance and stability of the new service, and interaction data to understand usage.
"For example, we may log whether a connection succeeded or failed, or record that 2 GB of data was used on a certain day," the company explains.
The routing server is based in the U.S., and it is selected considering location and performance for the best user experience.
Starting today, the built-in VPN feature will roll out progressively to users in the U.S., UK, Germany, and France. Currently, there is no timeline for expanding the service to more regions.
Firefox 149 also comes with Split View, a function that has been present in Google Chrome for a while, which allows placing tabs side by side in the same browser window. Mozilla highlights use cases such as planning, comparing, note-taking, and small administrative tasks, such as tax filing.

Firefox also now automatically blocks notifications and revokes permissions from websites that the ‘SafeBrowsing’ security system has flagged as malicious.
Firefox 149 also fixes multiple security vulnerabilities. The list includes 46 issues, more than half receiving a high severity score. Several of them are user-after-free flaws, out-of-bounds errors, JIT engine flaws, and sandbox escape vulnerabilities.

Mozilla released Firefox 149, incorporating a free, built-in VPN with a 50GB monthly data limit. This new feature utilizes a secure proxy server to route traffic solely from the Firefox browser, distinguishing it from the company’s commercial Mozilla VPN, which covers system-wide traffic. According to Mozilla, the primary purpose of this initiative is to provide users with a simple means of maintaining privacy while browsing, particularly when utilizing public Wi-Fi, seeking sensitive health information, or conducting online shopping. The feature is designed to mask the user’s location and IP address through this proxy connection.

Upon enabling the VPN, users gain access to 50GB of monthly traffic, with in-browser notifications alerting them when they approach this limit. The VPN functionality can be toggled on or off through a dedicated switch within the browser’s top-right interface, and users can further refine its operation by selecting specific websites—up to five—to be protected by the VPN. Notably, certain websites and essential services are excluded from VPN routing in order to maintain account sign-in functionality and ensure seamless reconnection, preventing disruptions in service.

Mozilla emphasizes a restrained approach to data collection, stating it will only record technical data pertinent to maintaining the service’s performance and stability, alongside interaction data designed to understand user behavior. Examples of logged data include whether a connection succeeded or failed, and the volume of data utilized on a given day; for instance, recording that 2 GB of data were consumed during a particular period. The routing server’s location is strategically selected to optimize user experience based on location and performance metrics. Currently, the rollout of this feature is commencing progressively within the U.S., UK, Germany, and France. The timeline for expanding the service to other geographic regions remains unspecified.

Firefox 149 also introduces Split View, a functionality previously seen in Google Chrome, which allows for the simultaneous display of multiple browser tabs within a single window. This feature is intended to streamline workflows such as planning, comparing products, note-taking, and handling administrative tasks like tax filing. Moreover, Firefox automatically blocks notifications and revokes permissions from websites flagged by the ‘SafeBrowsing’ security system as malicious. The release also incorporates fixes for 46 security vulnerabilities, a significant number categorized as high severity, including user-after-free flaws, out-of-bounds errors, JIT engine flaws, and sandbox escape vulnerabilities. Finally, the update includes a new SplitView feature, enhancing the browser’s usability.
