I'm using Windows 11 152.0.4 Firefox version I'm in Australia

I am using Firefox’s new built‑in VPN (not the standalone Mozilla VPN app). When I switch between USA, UK, or Germany, the browser successfully routes traffic through those regions even though the VPN icon remains grey. However, when I select Canada, Firefox appears to accept the region change but no websites load at all. The browser becomes effectively offline.

The following error appears in the console:

Code SearchSuggestionController found an unexpected string value: HTTP error 2

1. dedupeAndReturnResults moz-src:///toolkit/components/search/SearchSuggestionController.sys.mjs:639

fetch moz-src:///toolkit/components/search/SearchSuggestionController.sys.mjs:36 Troubleshooting already attempted:

Disabled DNS-over-HTTPS

Cleared DNS and HTTP caches

Tested in Private Window

Tested in Troubleshoot Mode (Safe Mode)

Restarted Firefox

Switched between multiple regions

Confirmed that USA, UK, and Germany work normally

Only Canada fails consistently

None of these steps resolved the issue.

Expected behaviour: Canada region should function like the other regions and allow normal browsing.

Actual behaviour: Selecting Canada results in:

Blank pages

No network activity

SearchSuggestionController errors

Browser appears offline

Other regions continue to work normally

Conclusion: This appears to be a server-side failure or misconfiguration in the Canada proxy endpoint used by Firefox’s built‑in VPN. The issue is reproducible and persists across troubleshooting modes.

Please investigate the Canada endpoint for the built‑in VPN.

I downloaded Firefox today and saw there was a VPN option but it is not working. It asks me to sign in and per the instructions the clickable icon at the top should now have an option to enable but it just asks me to sign in again. I am from Canada and it says my region is available for this program.

Hello. I recently started using the built-in VPN in Firefox.

According to the Use built-in VPN in Firefox information page, I should be able to see the data usage in my Settings. However, when i look there, I can see "Manage websites" block and the "Get more protection" block, but I cannot see the "Monthly Data Limit" indicator that's supposed to sit between them.

I am running Firefox 152.0.4 on Windows 10

Am I looking in the right place for the VPN data usage? Is there another place to find the Data Usage?

Thank you.

VPN working properly, then quits for no apparent reason, gives me a sign up / sign in screen [Screenshot 2026-07-01 111229], I sign in <sign in as subscriber>, error [Screenshot 2026-07-01 111537], VPN doesn't work (checked with check my IP), but Mozilla says I signed in! [Screenshot 2026-07-01 111649] What gives? [Tried rebooting already]

I am unable to activate the built-in VPN. I am in a loop of getting started -> Activate Firefox’s built-in VPN for extra privacy and protection' then I click 'Continue' and then I get again back to 'get started'. The built-in VPN never activates. I am signed in while doing that and I am using a macbook to run firefox.

Das VPN lässt sich in der neusten Version optisch zwar aktivieren, scheint aber nicht zu funktionieren. Die 50GB bleiben ständig erhalten und reduzieren sich nicht , trotz durch Test´s mit erhöhtem Datenvolumen. Auch erreichen mich bei aktivierten VPN wieder vermehrt SPAM und Ähnliches.

Auto updated to firefox 150 yesterday. What's new screen announced the rollout of the free in browser vpn had reached us (in Canada). Clicked the link to set up, went to screen to follow instructions. There's no vpn icon in the firefox menu bar, no matter what I do. (And I have done everything obvious.) Was the VPN not in the actual update I received or is this some bug/glitch? Thanks.

I have installed Firefox VPN, but it is disabled by default so I have to enable it whenever I use it . How can I change the default setting to make it on by default

Hi I'm running Firefox 152.0.1, 64 bit, english version from Italy. From last updates I learned that a built-in VPN is available for users. I looked for it everywhere in Firefox toolbars and menus, but I cannot find it. Am I stupid or VPN can be unavailable in my local version of Firefox? Thanks!

Pressing the VPN button on my browser allows me to star or stop vpn o,k. but I would like to know how much I have used in the current month so I can be sure of saving some vpn for special sites e.g banking. I would appreciate tour guidance please

hi, whenever i am trying to use the vpn on firefox, i either get a message saying Unable to find the proxy server Firefox can’t connect to the server at facebook.com What can you do about it? Try connecting on a different device. Check your modem or router. Disconnect and reconnect to Wi-Fi.

or on youtube, message shows Connect to the internet You're offline. Check your connection.

is there a way to resolve this issue. i currently set up the vpn to Location: Recommended
