Where is the free VPN?

The Firefox built-in VPN is offered in stages to users in the U.S., U.K., Germany and France, as mentioned in the Firefox 149 release notes. It is also offered to users in Canada, starting in Firefox version 150. It is not available to everyone, even if you are in one of these locales.

If the built-in VPN is available, you would see a VPN icon in the top-right corner of the toolbar, that opens a prompt to turn on the VPN. You would also need to sign in to a Mozilla account. For more infomation, see the Use built-in VPN in Firefox article.

If you wish, you can post your feedback about the Firefox built-in VPN to the Mozilla Connect thread.

Hi

That is not currently available in Firefox for Android. It may be available in the desktop copy of Firefox subject to location and whether you have been included in the beta test.

My ANDROID tablet running UI 8.0 got the VPN option several days ago, why has my Samsung S24+ running UI 8.5 not gotten the VPN feature?

This feature is experimental and is being introduced to the Firefox user base through a progressive rollout. It may not yet be available to all users.
