Today (7/11/26) Mozilla VPN began blocking all access to the Internet. When I turn it off, I can connect. When I turn it on, I can't. Am I the only one? So far I have:

• Reset the app
• Uninstalled all WAN network adapters and restarted (I notice for the first time that Mozilla Tunnel appears in the list after doing this)

It is interesting to note that Proton free VPN which I installed as an experiment, and ran with Mozilla VPN entirely off (system tray quit as well) also blocks all Internet traffic. So it could be one of those Windows update issues. This afternoon, all was well. I turned off my machine, turned it back on, and no browsing can happen with either VPN on.

Normally, Mozilla VPN works flawlessly, so I have no complaints--it's only a technical mystery to unravel.

Is there a bug in the code for v152? I need to connect to a ms office 365 email account with requires OAuth

The create new account process does not work, because it forces you to go through the whole (manual) process which then fails because you cannot select the Oauth option from Authentication method dropdown box - because its not there !.

This URL with the process to add OAuth: https://www.bing.com/search?pglt=419&q=setting+OAuth+in+thunderbird&cvid=22ed20c67b3843d58ddbc136bed2f174&gs_lcrp=EgRlZGdlKgYIABBFGDkyBggAEEUYOTIGCAEQABhAMgYIAhAAGEAyBggDEAAYQNIBCTExMjgyajBqN6gCCLACAQ&FORM=ANNTA1&PC=ASTS

fails at Step 2 because it does not let you complete to then go to Step 3 - because the account is never created !

How do I fix this ? thanks

On Saturday morning 27 June 2026 I tried to login my Orcon email account via Thunderbird (which I have been using for a long time). But my login didn't work, I got a message saying "login to POP3.orcon.net.nz with username habitation failed." On 30th June 2026 I reported the problem to Orcon.

Orcon gave me the following settings for Thunderbird. I have done that and even made a new account: Incoming Server Type: IMAP Mail Server: imap.orcon.net.nz Port: 143 SSL: Off Authentication: On (username and password required)

Outgoing SMTP Server: Mail Server: smtp.orcon.net.nz Port: 25 SSL: Off Authentication: Off

Since then I have spent many hours and going around in circles with Orcon's Technical Support to resolve this, but no luck. They blame Thunderbird. I used Thunderbird Troubleshoot Mode. The message that comes up reads: login to server mail orcon.net.nz with username habitation failed. Please can you check that your server settings above are correct? And if there is a bug? Irma

I am getting a lot of phishing emails. They all come from email addresses from "onmicrosoft.com". These I can find pretty easy. The other thing they have in common is this URL/'server name' in the Message Header "send.workwithshadow.com".

Is there a way to search and/or filter for text in the Message Header?

Thanks, Walter Cook

We use Thunderbird because of its flexibility across multiple OS and interfaces. We have only one PC using Windows, and that is a Microsoft surface running Windows 11. On that machine, emails are, from time to time, delayed, sometimes by 12 hours or more.

The emails come through normally on Android and Linux machines, and we had no difficulty on the Surface until we upgraded it from Win10 to Win10. The emails can also readily be accessed using a web interface to the provider's Apache server. Meanwhile, asking Thunderbird to get emails consistently reports "No new emails".

This is a very intermittent problem, with no discernable pattern to when it happens, or how long the messages get delayed.

Can anyone give me some pointers on where to start troubleshooting this?

unable to get Download Helper to initialize in my Firefox browser. i have checked and rechecked so many things. how can i fix this so i can dl videos from the internet and watch them?

Hello!

I use Nightly 154.0a1 (2026-07-10) (64-bit) on Windows 11. I'm trying new VPN feature from study and the VPN itself is working, but the location setting is completely broken. I have only two options for location Recommended and United States. Whenever I choose United States, nothing changes and my IP is always from subset of CIDR 63.245.208.0/20 which is geolocated in London, UK. I tried multiple IP addresses (by restarting VPN) and all of them are geolocated in London. Running traceroute also suggest that all of them which I get are located in the UK. Is there a way to fix this?

Before facebook using reCAPTCHA I can easily logo in my Facebook and Instagram account, but now I always failed to pass the reCAPTCHA， I report this to Meta no good reply. Only today I did the reCAPTCHA and then got a reminder that facebook cannot detect the reCAPTCHA. I still cannot logo on to my facebook and instagram account due to reCAPTCHA. How can I solve this problem. Thx

Hi, I have a Yahoo account in Thunderbird. Every time I try to create a folder, it doesn't appear immediately. I have to close Thunderbird and reopen it to see the new folder on my folder list. This doesn't happen with other email accounts, like Gmail or NetworkSolutions, only with Yahoo.

Thank you for any information on how to correct it, or whether other people are having the same problem.

after the last Firefox update the zynga game Farmville 2 will not load. It gives me a screen to fix mentioning chrome..but all efforts to manually fix referencing Firefox have failed. Odd that I can load the plain Zyngagames.com on Edge but it seems they too only load a "local" game that is not connected to any network. Help also mentions to make sure I allow to redirect but that "Options" feature to do so is not there. In fact it seems like the Firefox menu system is even much different and expanded. I will add the screens I have tried etc. Pop ups are allowed, turned off enhanced etc. but cannot find any reference to "third party redirects" Any suggestions are appreciated.

I changed ISP's this week and my computer connects via Ethernet cable through my router. I have no real issues accessing the internet. But after waking from sleep or restarting, Firefox displays the network login prompt. How do I get rid of it? Thanks.

I use Firefox on various computers, now I'm setting up a new one, and I don't remember either my Firefox password or how to access it one way or another with my own identity. What can I do?
