Firefox is adding a free VPN for all users - but can you trust it?

## Summary
Mozilla is launching a free virtual private network (VPN) service for users of it Firefox browser. Also: The best secure browsers for privacy in 2026: Expert tested "Free VPNs can sometimes mean sketchy arrangements that end up compromising your privacy, but ours is built from our data principles and commitment to be the world's most trusted browser," Mozilla says. "It routes your browser traffic through a proxy to hide your IP address and location while you browse, giving you stronger privacy and protection online with no extra downloads." There's no word on an independent audit yet, so we can't say whether or not the new VPN will be inherently secure -- but there have been no significant security concerns around the existing solution, so the baked-in browser version may be no different. However, as with Mozilla's traffic data cap, there is always a trade-off when you opt for a free VPN rather than a paid service, such as device protection limits, speed throttling, or limited server access. Also: Firefox users didn't want AI, so Mozilla is giving them a way to kill it If you want a free VPN that can do more than just protect your browser session, consider Proton VPN, Windscribe, or one of the other free VPN services we recommend .

ZDNET's key takeaways
Firefox is launching a VPN for its browser users.
The built-in VPN is free and arrives March 24.
Limitations mean you shouldn't cancel your current VPN.
Mozilla is launching a free virtual private network (VPN) service for users of it Firefox browser.
In
a blog post
published last week detailing upcoming updates with the rollout of Firefox 149, Mozilla said the VPN will be free and available to all Firefox users.
Mozilla's VPN
Mozilla's VPN has been around for some time as a standalone product, but as a frequent
VPN reviewer
and tester, I haven't seen it make much of an impact in a crowded, saturated marketplace.
You can sign up for the service, which offers around 500 servers in over 30 countries, to protect up to
five devices for $4.99 per month
, plus tax.

The new, browser-based offering will be available to Firefox users in the US, France, Germany, and the UK to begin with, with more countries likely to follow. It's free, unlike the existing paid solution, but you are restricted to 50GB of data monthly.
Can you trust the new Firefox VPN?
Mozilla is a nonprofit, and its Firefox browser is known as one of the more privacy-focused options around. Mozilla says it will apply its existing
data principles
and privacy-focused approach to its VPN.

"Free VPNs can sometimes mean sketchy arrangements that end up compromising your privacy, but ours is built from our data principles and commitment to be the world's most trusted browser," Mozilla says. "It routes your browser traffic through a proxy to hide your IP address and location while you browse, giving you stronger privacy and protection online with no extra downloads."
There's no word on an independent audit yet, so we can't say whether or not the new VPN will be inherently secure -- but there have been no significant security concerns around the existing solution, so the baked-in browser version may be no different.
Why offer a free VPN?
As Mozilla itself noted, free VPNs are usually associated with something sketchy -- such as suspicious activity, malware, or the sale of user data.
There's only a handful of trustworthy free VPN services out there, of which our
top choices
are Proton VPN and Windscribe. However, as with Mozilla's traffic data cap, there is always a trade-off when you opt for a free VPN rather than a paid service, such as device protection limits, speed throttling, or limited server access.

VPN server infrastructure costs money to run, so there has to be some form of revenue stream. This will apply to Mozilla, too, so introducing the VPN in-browser could become a funnel for more paid subscribers, who will then fund free usage. It might also serve as an incentive to lure some of us to switch from other browsers, such as Chrome, to Firefox.
Should I cancel my existing, paid VPN?
No. If you're a

## Expert Analysis

### Merits
- Also: The best secure browsers for privacy in 2026: Expert tested "Free VPNs can sometimes mean sketchy arrangements that end up compromising your privacy, but ours is built from our data principles and commitment to be the world's most trusted browser," Mozilla says. "It routes your browser traffic through a proxy to hide your IP address and location while you browse, giving you stronger privacy and protection online with no extra downloads." There's no word on an independent audit yet, so we can't say whether or not the new VPN will be inherently secure -- but there have been no significant security concerns around the existing solution, so the baked-in browser version may be no different.
- If you're already a paid subscriber to a standalone VPN service, this new offering -- while likely to benefit some Firefox users -- isn't necessarily going to work as a full replacement.
- The Firefox VPN will probably be best suited for casual browsing and for users who want to protect their online sessions or hide their IP address, and it will likely benefit those who want to learn about VPNs.

### Areas for Consideration
- As such, it might be useful for accessing geo-locked content or reducing the risk of being tracked or spied upon, but it doesn't offer the other privacy and security features found in independent VPNs, such as encryption protocol options or specialized streaming servers.

### Implications
- When you buy through our links, we may earn a commission.
- When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions.
- This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay.
- If we have made an error or published misleading information, we will correct or clarify the article.
