Abstract:
Mozilla announced that from November 10 to January 31, 2027, the free VPN service built into the Firefox browser will temporarily remove traffic restrictions. During the event, all users who log in to a Mozilla account and use this feature will receive unlimited data access without paying extra or installing a standalone app.
Mozilla stated that the launch of this limited-time upgrade event coincides with the end of the year holiday travel and shopping season, hoping to provide users with a better privacy protection experience when traveling, online shopping, and daily browsing the web. Compared with the previous free traffic limit of 50GB per month, the new policy will allow users to use the service unlimitedly for nearly three months.
The core function of Firefox's built-in VPN is to hide the user's real IP address and reduce the ability of websites to use IP information to infer geographical location or track user behavior across websites. Mozilla emphasized that users do not need to exchange browsing data to obtain privacy protection. The company will not sell user browsing data, nor will it interfere with user experience through advertisements, and will not record the content of websites visited by users.
Mozilla pointed out that in public network environments, built-in VPN can provide additional protection. For example, when users connect to shared Wi-Fi in cafes, airports, hotels, or at the homes of relatives and friends, a VPN can help hide information on visited websites and reduce the possibility of network operators obtaining users’ browsing habits.
In addition to the privacy protection function, Firefox's built-in VPN also supports changing network location. Users can choose to have network connections appear as coming from other supported regions, making it easier to access hometown news or use region-specific network services while traveling abroad.
However, Mozilla also reminds users that VPN does not mean completely anonymous surfing. Websites can still identify users through account login status, cookies, etc. Additionally, this feature will not clear browsing history saved locally on your device. To prevent access records from being saved in the browsing history, users still need to use Firefox’s private browsing window feature.
Mozilla also emphasized that the current free built-in VPN only protects network traffic generated within the Firefox browser and does not cover other applications on your computer or phone. If users want VPN protection for their entire device, they need to subscribe to the paid version of Mozilla VPN service.
It is understood that Firefox’s free built-in VPN currently supports desktop and Android browsers, and iOS version support is also under development. Users only need to register and log in to a Mozilla account to enable the function through the VPN icon in the browser toolbar on the desktop, while Android users can find relevant options in the browser settings menu and complete the configuration.
In fact, when Firefox officially launched its built-in VPN service in 2026, it attracted widespread attention with its 50GB free monthly traffic. Mozilla claimed at the time that this was one of the first products in a mainstream browser to provide free built-in VPN functionality, aiming to integrate privacy protection capabilities directly into the browser instead of relying on third-party extensions or independent software.
Industry insiders believe that although the opening of unlimited traffic is a limited-time event, it reflects that Mozilla is further strengthening the differentiated competitive advantage between Firefox and other browsers. In a context where artificial intelligence functions and advertising businesses continue to become new focuses for browser manufacturers, Mozilla still regards privacy protection as one of the most important core selling points of Firefox.
According to the plan, this unlimited traffic activity will last until January 31, 2027. By then, Firefox’s free built-in VPN will restore its original 50GB monthly traffic limit. Mozilla stated that it will send relevant reminders to users before the end of the event so that users can understand service policy changes in advance.
