Firefox doesn't connect to custom DNS provider when DNS-over-HTTPS is set to "Max Protection"

Hello guys, as in title - I use custom NextDNS set of rules on DNS-over-HTTPS. As of today, Firefox can't connect to the provider. AFAIK Troubleshoot Mode is also affected. The other devices using NextDNS on my network work just fine and when I set the DNS to work system-wide as a kind of workaround, I don't get an issue. Same when I use other DNS-over-HTTPS options in the Firefox Preferences. Yesterday the problem didn't occur and I haven't performed any updates since yesterday - both Firefox and NetworkManager seem to be up to date.

Additional info: OS: EndeavourOS (Arch Linux) Firefox version: 129.0.2

If any other info is needed, I'll be happy to provide it to you.

Registering a Security Key

I'm trying to use a security key for my Vanguard site. I've tried with Firefox, Microsoft Edge, and Chrome. I can get to almost the end but get stopped-- I can't get no father to "connect and activate." I get a message saying--"Vanguard is requesting extended information about your security key which may affect your privacy. Firefox can anonymize this for you but the website might decline this key. If declined try again." I talked to Vanguard for help but they didn't know how to help. The key is uTrust FIDO2 NFC. USB-A NFC Certified Security Key. I believe the problem may be that this key will link all my accounts in Firefox ( and will also link if I use any other browser.)

I got the following from the internet: When it says authenticators it means Security Key.

Using an authenticator for one account is safe, but allowing a website to ask for extended information for multiple accounts using the same authenticator can permit that website to identify a link between those accounts. If you are concerned about having accounts linked together in this way, you should either deny extended information when prompted, or use different authenticators for the different accounts. This linkability is based on the authenticators, and not on your browser. If you use the same authenticator with different browsers, websites can still identify a link between multiple accounts. Can this be solved? Thanks joek90ros@aol.com

I use both Firefox and DuckDuckGo. I also have NordVPN. Recently, I have been getting warnings through NordVPN that both Firefox and DuckDuckGo represent vulnerability risks. I have been using all three programs for some time now. This warning from NordVPN is something new. Is there a vulnerability risk or is there some in compatibility between new versions of these software packages?

I am using Windows 11 on a Microsoft Surface Pro 9.

Thanks for your help.

Firefox IS Leaking Personal Information (email address)

This message is to inform you that my email is being leaked from my Firefox browser, in hopes that Mozilla will provide a fix ASAP (if it hasn’t already done so in the latest version?). This leak was made known to me after visiting several websites (sites I've visited previously and sites I’ve NEVER visited before!), where I will receive an email very shortly, if not immediately after visiting and closing the browser tab for the website. (These are legitimate sites that are selling a product and, typically, very politely asking if I need more information, etc. ).

After noticing this, I got in the habit of clearing Firefox memory frequently, if not after every site I visit; but especially when my email is required to login. However, today I just notice that my email address is “permanently” located within the Firefox browser; and have to wonder if this could be how websites are getting my email… The email is located in the Firefox addon Video DownloadHelper app. The Companion App within Video DownloadHelper requires a payment, license #, and email to install. And, when looking thru its new menu today, I noticed my email (the same one I get messages from after visiting sites) is right there within the Video DownloadHelper menu (click on VDH icon, click on gear icon, click on More settings…).

So, I don’t know for certain whether my email is being compromised after logging in to a website and not immediately clearing memory after leaving the website OR if the compromise is from the Companion App within the Firefox Video DownloadHelper app, OR possibly both(?). If it is being leaked from Video DownloadHelper, I would greatly appreciate it if Mozilla would implore upon the VDH crew to remove it from the app.

And, if you can, I would greatly appreciate an email letting me know if/when this has been fixed! Thanks! Regards, Dave
