I get this message from Thunderbird on my desktop computer on app start up: ]Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

This started suddenly about a week ago.

I have Thunderbird on laptop that works fine.

How can fix this?

The exact link live.thunderbird.net is not something Thunderbird would point to. But it is used to point to the start page, accessed in Thunderbird via Go > Mail Start Page, and resolves to https://start.thunderbird.net/en-US/release/.

Thunderbird is complaining about a certificate error.

Does the error go away if you do

The full instructions: 


* Start Windows in safe mode with networking enabled - https://support.microsoft.com/en-us/help/12376/windows-10-start-your-pc-in-safe-mode
* Still In Windows safe mode, start Thunderbird in Troubleshoot Mode - https://support.mozilla.org/en-US/kb/troubleshoot-mode-thunderbird

Does problem go away?

- If no, then cause is either: bug in Thunderbird, a setting, file or folder (something) in your Thunderbird profile, your mail provider. Please attach to the bug report or support topic a file created from Help | Troubleshooting | copy text to clipboard

- If yes, the problem is gone, then (still in Windows safe mode) ... start Thunderbird normally -- If problem is still gone, then cause is likely a program loaded during windows startup. Possibilities include: antivirus software (AV), virus/malware, background downloads such as Windows or other program updates, to name a few. For AV information see https://wiki.mozilla.org/Thunderbird:Testing:Antivirus_Related_Performance_Issues -- If problem came back, then cause is likely a Thunderbird add-on - eliminate them by disabling add-ons one at a time in Tools | add-ons | extensions and restart Thunderbird after disabling (if you have many add-ons, try disabling half of them at a time)

- If results are unclear ... possibilities include temporary conditions such as contention from other running programs, downloads related to windows update, ...

I am running thunderbird on ubuntu 23.10 with all the latest patches/updates and I get the same message. This all started today after 16:32. Any ideas?
