Mozilla apps can't get Cloudflare to verify while using NordVPN

more options

Apps Firefox and Thunderbird are having problems opening links to webpages. In particular, Cloudflare cannot verify (it just cycles between a checkbox "Are you human?" and a browser check) when I use FF.

I use Win11 with NordVPN, but this wasn't a problem before the latest Win11 update. (It also seems to have affected TB reconnecting to Ymail.) I'm now using Chromium to read my Ymail avoid Cloudflare verification, but I'd rather keep using FF and TB apps.

I've been going though Cloudflare, NordVPN and Mozilla online help for a few days now, and I think I've tried everything there.

Thoughts?

Chosen solution

In the most recent version of Thunderbird, I was able to connect to my Yahoo mail account via the normal use of the server settings tabs. All my normal PC Windows-11 settings, browser extensions, and VPN were operating at that time; so please consider the issue closed. Thanks for your time and effort.

Yes. Unfortunately, the misbehavior did not change.

You appear to have several content blocking extensions installed. Did you check whether they aren't causing this problem ?

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, DuckDuckGo PE, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block content.

Do you have the same issues when off VPN?

All,

The FF problem is only present when NordVPN is running. However, FF (and Thunderbird) worked previous to the last major Win11 update, and currently Chromium also (mostly) works although I continue to use FF most of the time. (Some login webpages on Chromium also have an issue with NordVPN.)

I've tried running FF without extensions in safe mode, but that doesn't help. VPN may be quaint, but I'm not prepared to drop it. So I'm looking at dropping either FF (for Chromiun or similar) or NordVPN (for a more compatible VPN). What I do with Thunderbird will be addressed afterwards.

Best regards.

Since you're issue is not a browser issue and you're using VPN, why not try Mozilla's? https://www.mozilla.org/en-US/products/vpn/ Give it a shot and see if you have the same issues. I also found these links about your issues with NordVPN. https://support.nordvpn.com/Connectivity/1087249732/I-can-t-reach-some-websites-with-VPN-connected.htm

Does it still happen in a new profile? An easy way to test a new profile is to install Developer Edition and see if it happens there or refresh your existing profile.
