I’ve been using TB for years without problems but since 30 Oct 2024 have not been able to send/receive gmail on my desktop computer. I get an “Add Security Exception” pop-up. Clicking on “Get Certificate” results in “No Information Available” and clicking on “Confirm Security Exception” results in “Send Message Error”. Strangely TB continues to work on my laptop! I notice that some other users have had a similar problem but I’ve not found a solution. Does anybody know the cause and cure?

Solved it! In the last few days my Norton 360 upgraded to version 24.10.9535 and it was the email virus checker that was causing the Thunderbird security exception pop-ups. Temporarily disabling this for 10 minutes allowed TB it operate normally. I then updated Thunderbird from version 115.10.1 to 128.4.0 (Nebula) and re-enabled Norton’s email virus checker. All now working OK.
