If it is available, and you can see it then yes.

However although it has been rolled out to US, Canada ~ UK, France, Germany it has not come up on my W11 Fx 150.0.3

Just about update to 151.0

If it is available I will update.

No update means it is not available on My W11, Ubuntu, Linux, Debian , Raspberry OS even though I am in the UK and FX is up to date.

UPDATE:

Yes !  . . . The fresh new update invites me to use the free VPN

Thanks! I will makes sure I am updated to the latest version to see if I can find the VPN!!

is free VPN available on my phone like it is on my laptop?

If by phone you mean iOS or Android.

There may be a Early Access (Phase 0) Release as early as Firefox 151.0 for Android though like the built-in VPN on desktop Firefox was limited starting Fx 149.0. it may be in limited places in testing on Android.

Thanks! I will makes sure I am updated to the latest version to see if I can find the VPN!!

amoun was referring to desktop Firefox and not Firefox for iOS or Android.

Since you posted this thread with Firefox for Android and mentioned phone, I moved this thread from desktop Firefox to Firefox for Android section.

Android

We will start shipping built-in VPN in Firefox Android with version 152 progressively in the following countries: US, UK, DE, FR, CA
