You can now use1 Firefox’s free built-in VPN with no data limits until August 31, 2026.

Mozilla is also temporarily expanding the list of VPN server locations you can proxy traffic through, up from the current set of 5 locations to 28.

The Firefox 151 release in May added the option to select from a list of VPN servers (though it’s a feature yet to be enabled for everyone), which is handy when location matters more than speed (Firefox VPN selects the fastest VPN server by default, typically the one closest).

The extra server locations during the promotion: Australia, Austria, Belgium, Bulgaria, Chile, Colombia, Denmark, Finland, Ireland, Italy, Malaysia, Mexico, Netherlands, New Zealand, Norway, Portugal, Singapore, South Africa, Spain, Sweden and Thailand.

On September 1, the Firefox VPN will drop back to a 50GB monthly data limit and a reduced set of server locations for free accounts. The limited-time promotion presumably aims to whet the collective appetite for features found in the paid Mozilla VPN service.

The Firefox built-in VPN is included free with Firefox in the US, the UK, France, Germany and Canada. It can only be turned on by signing in to a (free) Mozilla account, but no additional add-ons or extensions are needed; it’s built into Firefox and works on Windows, macOS and Linux.

Though browser-only (it’s not a system-wide VPN) it has some useful features like server locations and setting per-site exceptions – which stops traffic being rerouted for a specific set of websites, saving the hassle of having to turn the VPN on and off.

Firefox VPN is browser-only rather than system-wide, but does include per-site exceptions. This will prevent traffic being rerouted for specific websites you set, which is handy if you don’t want to toggle the VPN on and off to access something where your real location is needed.

  1. Assuming you live in a supported locale and Mozilla has granted you access to it. On 4 devices I use the browser on (in the UK), only one has Firefox VPN available in it. As a progressive rollout, access is granted server-side. ↩︎
