The VPN works if I Enable DNS over HTTPS using Default Protection, however if I select Max Protection and use Cloudflare, it does not work as it cannot resolve DNS.

If I disable the VPN or select Defualt Protection, DNS works again.

Windows 11 Pro 25H2 26200.8313 Firefox 150.0.1

Hi All,

I have tried the new free browser VPN however it does not load pages if I am using a custom DNS (Quad9) and have DNS over HTTPS enabled. Is this expected behaviour and just a limitation of the VPN?

Any advice would be much appreciated.

I am attempting to use Firefox's new built-in VPN to hide my browsing and use sites that are restricted like Reddit on a common wifi while I am on breaks. It worked on these common wifi systems for a little bit, but last week I believe, it just stopped working one day. Now, when I turn on the VPN, the only thing Firefox will do is display the following error: ~~~~~ Unable to find the proxy server

Firefox can’t connect to the server at [insert url here] What can you do about it?

Try connecting on a different device. Check your modem or router. Disconnect and reconnect to Wi-Fi. ~~~~~ I was originally running Firefox 149 via snap on Ubuntu, but I just uninstalled the snap package and switched to 150.0.1 via the Mozilla APT repository and I am getting identical behavior. Is this just a bug, or is it possible the administrator here has explicitly blocked Firefox VPN? Is there anything else I can do about it, since connecting on a different device doesn't help me, I can't check the modem or router, and disconnecting and reconnecting does nothing?

I tried the firefox VPN. I Followed the instructions at:

https://support.mozilla.org/en-US/kb/built-in-vpn#w_are-any-websites-excluded-from-vpn-protection

But no 'VPN' button appears when I sign in (I am in a valid country and was told about the VPN by my browsers update). I have tried restarting and checking the toolbar, but the VPN button that is supposed to be there is not.

I use Windows 10 and have Nord VPN. I installed Firefox VPN and turned off Nord. Now when I open Firefox all the articles are gone. If I turn on Firefox VPN all the sites say "Unable to find proxy server", I went to settings network and selected "no proxy" but still the same. Is there a way to fix it if not how do I delete Firefox VPN. Thanks.

It was announced under update 150.0.1 that a 50GB Free monthly VPN was available, however this is not the case in Brazil.

Is this a bug? Is there a due data for the activation? Is there any farther configuration needed to make it work?

PC / Win11

Thank you!

I enabled the Firefox browser VPN as a test and then disabled it, after the Google search no longer worked.

Error says Google.com is unavailable, can't connect to servers etc.

Any ideas how to fix it ?

I'm in Canada, when i updated the first Firefox instance had VPN show up but when i opened another it did not (the one with my Firefox account). When i opened a third it was also available.

How do i get it on my main profile which has this account, i use multiple Firefox instances to separate my browsing (Reddit, main, shopping).

The Firefox browser VPN option and toolbar button for Firefox 150 was originally showing up after a recent update (was not signed into the browser), but when I signed into the account as needed to activate VPN, the VPN toolbar button and options under security settings disappeared. I can't find the vpn button to add back under the 'customize toolbar setting' as suggested. And when I go under privacy and security settings, the VPN section is no longer there. How do I get the VPN options back? I tried signing out of Firefox and then back in. I tried disconnecting 'sync' from the computer and that didn't change anything either. I've updated the browser on all devices I'm signed into to 150.0.1. The VPN toolbar button or setting option does not show up on any device I am using. The only browser I initially saw the VPN options on was the browser that I wasn't initially signed into, and it disappeared after I signed into the browser with the account.

None of the suggestions at the following help page work to get the VPN options back in the browser settings, or toolbar: https://support.mozilla.org/en-US/kb/built-in-vpn?utm_source=www.firefox.com&utm_medium=referral&utm_campaign=whatsnew-150#w_turn-on-vpn-in-firefox
