Mozilla just announced a major privacy upgrade coming to Firefox: a free built-in VPN rolling out with Firefox version 149 on March 24, 2026. No extra downloads or extensions needed—once the update hits, you’ll see a simple toggle to turn it on and hide your IP address and location while browsing in Firefox.
Key Details on the Free VPN
- Data cap: 50 GB per month (resets monthly)
- What happens after 50 GB? The VPN likely turns off automatically until next month (Mozilla hasn’t confirmed yet)
- Speed & servers: Not specified yet—expect standard VPN performance (good for browsing, streaming, light gaming)
- Why free? Mozilla already sells a paid Mozilla VPN (no data cap, more servers). The free tier is a “try before you buy” hook that boosts user privacy without costing them anything extra.
This is a huge win for privacy-conscious users. Unlike shady free VPNs that sell your data to survive, Mozilla has a strong track record of protecting user privacy—no ads, no tracking by default.
Why You Should Always Use a VPN (Quick Reminder)
- Hides your IP from websites, trackers, and your ISP
- Encrypts your traffic on public Wi-Fi (cafes, airports, etc.)
- Bypasses some geo-restrictions (though paid VPNs are better for Netflix, etc.)
- Even incognito mode doesn’t hide your IP—VPN does
Free VPNs are usually bad news (data harvesting, slow speeds, malware). Mozilla’s free tier is one of the rare trustworthy options.
