Windows 11 Pro Mozilla Firefox 152.0.4 (64-bit)

When creating a passkey for my Mozilla account, the Windows Security passkey program insists on using my old gmail.com address instead of my new protonmail.com address.

How can I purge Mozilla records of my gmail address and use my protonmail address?

Many thanks

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.

Hello, I hope you are well.

All videos played on my FireFox browser are slowed. This happens on any video playing, including on YouTube, even when the video is on 1x speed and is not slowed. It has been getting progressively slower over the past months, and was not fixed after I uninstalled and reinstalled FireFox. Please kindly assist.

I changed my browser to the latest version of Firefox, but then I lost all streaming websites (youtube, Netflix), and password autofill. Luckily I had 2 firefox browsers so on the other one I did reset and can steam again there, but I lost several shortcuts and other extensions such as autotranslate. It's just gone. Colors and pictures are on both. And I can't change back the browser that has the newest version. So now I'm stuck switching between browsers depending on what I want to do. Wish I had never changed that browser. Has ruined my computer. I've spent days trying to fix and change things.

Everytime I restart and open firefox and then try to access facebook, sometimes google, n=some news websites and probably other apps, I get a captcha, but it repeats no matter how many times I get it right.

I was advised to do this, but it's still happening: https://www.youtube.com/watch?v=6fX0_wiVKhw

But even that's stopped working.

I cannot access facebook and I need it for work (small org, no IT section to ask), and can't access some new sites.

I've gone to basic security settings, but that doesn't help.

What to do?

Why does Firefox take wild guesses at what folder I want something save to. I just downloaded 108 files to the same folder and Firefox never caught onto where I wanted to save these files. It just kept pitching randome "default" folders all over my computer. How can this possibly be a desirable behavior?

My computer was hacked a month ago, well... I got phished when I was sent an email that looked like it came from a client, it was a bit premature to receive a file from her but... it was very late, I wasn't at my best, and there it is. I always thought I was savvy. So. I did catch it in time to save my Google account and they didn't succeed in getting at any money, did lose my longtime alt-email address. My computer tech was able to restore most of Thunderbird, except for all my client information (18 years' worth), which I theorize is because the bad file was filtered into my client folders so those 2 main/many subs were deleted (or it could be because those client folders and a couple others missing were near the bottom of the folder tree and the tech guy's backup program failed at that point, he did try again but no luck). Fortunately I still keep a paper schedule so I was able to figure out who to talk to, and the autofill feature of TB was able to give me most of the emails I needed. [I have since learned about and have moved my Profile into my Documents in a separate folder so that my cloud backup picks it up every day (idrive). I really think it should be a LOT LOT easier to find and utilize the information on the Profile because EVERYONE should be backing that up every day, and the best way is to automate it. [My tech guy (re)installed Windows 11 Pro, I had Home by preference, have a tutorial from a trusted source about going back to Home without losing anything, because I do not need or want the architecture of Pro. But not doing that until I get my computer stabilized.]

All that said, to get to the point. When I collect email in TB (I have a gmail account using POP into TB as I do not like syncing and use TB to track), I usually have more than 200 emails at a time before I d/l into TB. Several times each d/l session, I get the following error message (header is cut off, it just contained my email address):

<<Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.>>

I have write privileges and there is plenty of disk space. I press OK and the d/l continues for a few more emails and then stops. I then press F5 again to start d/l again. Several times a session. There is no information about which folder isn't there or what is missing or causing the error.

It appears to me that the filters are telling TB to filter into a now-nonexistent folder. I did reconstruct my client folders, but plenty of room for error there I imagine (I use QuickFolders and that actually told me which of the visible tabs no longer existed). My old laptop died in the process of all this so no longer have another version of TB as a guide. I have 367 filters (been using TB since Eudora went away), but they are only searchable by name of filter, not by possibly now-missing folders.

1. I assume that this error only means the email isn't filtered, it doesn't mean it has been deleted or anything. yes? Or am I totally wrong about the meaning of this error message, and if so, please help! 2. What can I do to fix the error? With 367 filters, it would be nice if there were some way I could figure out a way to know which filter is failing, if indeed this is a filter problem?

Thank you for any input about this. I have tried and tried to figure this out.

All best wishes, --Victoria
