Mozilla is rolling out a free built-in VPN for Firefox, set to launch with Firefox 149 on March 24.
Privacy concerns often arise with free VPN services, particularly when unclear data practices put user information at risk. Mozilla says its VPN is built on its core principles of trust and privacy, avoiding arrangements that have raised questions in the past.
The new feature routes browser traffic through a proxy, masking a user’s IP address and location while browsing, without requiring additional downloads. At launch, users in the United States, France, Germany, and the United Kingdom will receive 50 GB of monthly data.
Mozilla plans to introduce updates giving users more control over key settings, stronger background protections, and new tools designed to enhance everyday browsing.
In addition, Firefox is rolling out productivity and optional AI features. Smart Window (formerly AI Window) offers in-browser assistance such as definitions, article summaries, and product comparisons without leaving the page. The feature is opt-in, with a waitlist for early access.
Firefox 149 also introduces Split View, allowing two webpages to appear side by side in a single window for easier multitasking and comparison. Tab Notes will let users attach notes to individual tabs, helping them track information and resume tasks efficiently.
“The roadmap for Firefox this year is the most exciting we’ve developed in quite a while. We’re focused on building the best browser, and our upcoming features are shaped by feedback from our community,” said Ajit Varma, head of Firefox.
“We’re improving core fundamentals like speed and performance, while launching innovative open standards in Gecko to keep the web open and diverse. At the same time, we’re prioritizing features that give users real power, choice, and strong built-in privacy protections—something only Firefox can deliver,” Varma added.
