Good morning. I am using Thunderbird version 115.16.2 (32 bit). Several days ago when every I attempted to get email by clicking on the "Get messages" button on my menu bar, nothing happened. If I went through the menu (File -> Get messages for -> email address, I would receive a box message titled "Add Security Exception". I have added a screen shot image. If i clicked "Confirm Security Exception" I could then receive mail the way I normally do by clicking on the "Get Messages" button on the menu bar. But the next day after booting my computer, I would need to repeat this once again. This is not normal. Is it an issue with Thunderbird or should I take this up with my server provider. Thanks Pete
