Firefox 149 ships with a VPN that gives you 50 GB a month—then politely reminds you it’s still just a browser plug-in, not Mozilla’s real VPN.
The update adds a proxy toggle in the top-right corner that routes only Firefox traffic through a U.S.-based server. Sign in with a Mozilla account and you get 50 GB each month; in-browser alerts nag you as the limit approaches. You can restrict the proxy to as few as five websites to stretch the quota, and some sites are hard-coded to bypass it so log-ins don’t break.

Mozilla says it logs only technical data “whether a connection succeeded or failed, or that 2 GB of data was used on a certain day”—and nothing that ties back to individual users. The routing server is chosen by location and performance; there’s no option to pick your exit country.
Right now the feature rolls out only to users in the U.S., UK, Germany and France. Mozilla has not said when, or if, it will expand elsewhere.
Firefox 149 also lifts Chrome’s Split View trick—drag two tabs beside each other in one window—and auto-blocks notifications from any domain that Firefox’s SafeBrowsing flag marks as malicious. The release patches 46 security holes, more than half rated high severity, covering use-after-free bugs, JIT mis-compiles and sandbox escapes.
At 50 GB the proxy is generous for casual browsing, but it’s still a browser-only shield. If you want system-wide cover, Mozilla will happily sell you the full Mozilla VPN—no quota, no geographic lottery.
