Firefox 社群討論區

I live in Europe, where this stupid age verification law is in effect. I get around this by using a VPN. The problem is that I have two Firefox profiles set up with the same VPN and the same country. The issue occurs on X (formerly Twitter). On one profile, the VPN works as it should and I no longer need to verify my age, but on the other profile, the VPN has no effect and X (Twitter) asks me to verify my age. Yet the VPN is definitely enabled. I’ve cleared the cache and cookies, but nothing helps. It’s driving me crazy. Does anyone have any idea what the problem might be?

Using version 153 on Windows 11. I have never been able to activate the VPN. I have tried ALL of the suggestions on the support site, permissions, policies, customize toolbar, etc. There has never been any icon to activate. Obviously, this has been going on for months. Thanks.

I read the article about having 50 GB of free VPN use after I updated Firefox today to version 149.0; however, I don't see anywhere where I can enable the VPN. I've checked in the "Customize Toolbar" section, and I still couldn't find anything. I don't understand, the article made it sound like I should have access, but I've also read that it's not out for everyone yet?

The way you use VPN is you can either have it turned off, or turned on with exceptions you can put in a list. I'd like to be able to do the opposite, have it mostly turned off, except for some websites that require one to view. This is a QoL feature I would like in a future update.

German: Kein intergiertes VPN bei ver. 152.0.5 Win 11 Pro privater Rechner und angemeldetem Konto verfügbar. Wie bekomme ich diese Funktion? English: There is no integrated VPN with Ver. 152.0.5 Win11 Pro, private computer and signin mozilla account available. What to do to get the function?

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.

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]

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.

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

I am reporting a technical issue regarding the built-in Firefox VPN feature. It was fully functional in my location (Czechia) until June 15, 2026, but it suddenly disappeared from my toolbar and customization menu on June 16, 2026.

Despite following the troubleshooting steps provided in the official help article "Unable to find the built-in VPN in Firefox," the feature remains unavailable.

Here is a summary of the diagnostic steps I have already performed:

- Data Collection settings: Confirmed that "Allow Firefox to improve features, performance, and stability between updates" is enabled.

- About:studies: I have checked my active studies as shown in image_464983.png. There is no "VPN - MVP Beta Holdback" study listed that would explain the removal of the feature.

- About:policies: The Enterprise policy service is inactive, and there are no restrictions blocking IPProtectionAvailable.

- Account management: I have signed out of my Mozilla account and signed back in, but the VPN icon did not reappear.

- Installation: I have performed a clean reinstallation of Firefox, which did not resolve the issue.

I have also checked the toolbar customization menu and the overflow menu, but the VPN icon is not available.

Since this feature was working perfectly until yesterday, could you please investigate if my account profile has been excluded from the current rollout or if there is a regional issue affecting users in the Czech Republic?

I have attached my about:studies screenshot (Screenshot_about_studies.png) for your reference.

The new Firefox built-in VPN, rolled out to Australia this week, is not redirecting to the chosen country location.

Despite selecting either US or UK in the country list, websites are still identifying me as located in Australia.

For example, despite VPN being on and US selected, cunard.com still redirects me to my home location of Australia (see https://www.cunard.com/en-au in address bar). Screenshot attached. Other websites similar.

Hello, I am experiencing an issue where the built-in Firefox VPN feature has completely disappeared from my browser interface. I cannot see the icon on the toolbar, and the feature is not active. Could you please clarify if this feature has been geo-restricted or temporarily disabled for certain regions, or if there is another hidden preference I need to modify to restore it? Thank you for your assistance.

The Firefox built-in VPN button disappears from my toolbar as well as from my customized toolbar options.

I wonder what is happening and I would like to recover it.
