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.

So that even if I am in a different program or app--such as my email Inbox--I can toggle to my Home Page by clicking on the Home Page widget. How can i do that? i'm running Windows 11 and a Firefox browser.

So I got a new PC, and installed Firefox on it. When I try to log into my account on there it goes to the loading page that shows the Mozilla logo and below it says "is verifying your browser..." with a spinning loading ring. The problem is that it won't do anything else but this. I have tried Refreshing Firefox, going into Troubleshooting mode, and just waiting. But after all of that, it is still stuck on the loading page described above. Nothing is happening but the loading ring forever spinning. I can not sign into my account at all because I can't even get to the page to do so.

How do I fix this?? I really need all of my stuff on this new computer. (I'm writing this question from my old computer since I can't even log into the Support because of the same issue)

Hello all:

After migrating to a new machine I finally have TB set up and running nicely. As I checked the individual settings and C: folders for the e-mail accounts under the server settings for each account (there are two, law and business), and the local folders (for long term e-mail storage, under Local Folders, Local Directory settings), I discovered the C: folder for the Law e-mail account is gigantic - when I check the properties in File Explorer it comes back as 331 GIG, yes, gig. More disturbing is that most of this appears to be "dark matter" that does not "show up." I total the visible files and folders inside that location and it is roughly 150 meg.

For comparison, the folder directory for Business e-mail account is only 24.9 gig, and the directory for the local folder for long term e-mail storage only clocks in at 11.1 gig.

Any ideas why the law firm e-mail account C: drive storage would be this large, with so much of it not visible?

Thanks for any thoughts.

Thunderbird updated to 148.0 today and I'm no longer getting mail from my AOL accounts (iMap). I get a screen that appears to be a signin for Oauth2 but when I enter my account info I get an AOL screen that indicates I should login with a browser already used.

I use Thunderbird when Postbox acquired another. I am using 2 computers - desktop, old (10+ years), still Windows 10, and 2 two emails; new laptop (traveling), Windows 11. I download Thunderbird and set up my accounts - gmail.com and twc.com. Troubles with gmail.com, but finally I set up. However, I can't set up twc.com. I like twc.com-- no reason. (Time Warner Cable (twc) bought Spectrum. ) I can login twc.com webmail. Not Thunderbird. I looked carefully set up, Thunderbird searched, found "Host: mobile.charter.net" (Huh?, , continue, enter my password - "Error: ---". I removed VPN Windows 11, no difference. (Curios, my laptop and Firefox, my bank rejected connection. My desktop and Firefox still connects! I dread the day must update.)

I am look forward yours reply. (Maybe Spectrum is searching to dump twc.com.) Jeremy Fields P.S. I wrote with my desktop - windows 10 -, my new laptop (windows 11) is problems

Hello I hope you can help me. I signed up for the Mozilla VPN yesterday but have decided to end it. It is within the 30 day refund window. How do I receive my refund please? I did cancel it under the cancellation button but it did not offer my refund. It said I had the service for the remainder of the year but will not renew at the next renewal date.

The reason I am cancelling is because when trying to access youtube, google says I have to sign into a google account where before I did not have to do that. I canceled my google account years ago and am a avid firefox user. thank you for your time.

I also downloaded the app to my phone and may have signed in that way as well. Thanks.
