Even since Thunderbird 141.0 (64-bit) I've had two annoyances. I'm calling them that because it does not stop or prevent me from getting my email, that would be a problem. Here are my two annoyances: 1A. I have a message filter set up to these conditions. Match any of the following From isn't in my address book Personal Address Book From isn't in my address book Collected Address Delete Message This message filter is for an account that should not be receiving important emails. I wanted all of the junk emails emptied so I would not have to intervene. There are emails coming to this account, but not of great importance nor frequency. Those are in an address book. 1B. This is on my primary account. Match any of the following From contains (I enter email address here) Delete Message Since I use this account for business/personal use, I filter out spam/junk email this way. The annoyance is the filters are not deleting the messages as they should and I am having to open the message filter on each account and click on the Run Now, and then it works. It is not 100 percent of the time not doing what it should, but about 65 percent of the time. I've used these two message filters for years and they have always worked. This annoyance only showed up in version 141.0 (64-bit) (+ the ESR Version - see below). 2. My second annoyance is when I click on New Message, then it creates one and I go to Insert then click on Image then Choose File (and pick one) then click Open then the square box appears and I click the OK button. As soon as I click OK, it throws me out of the email/message that I am editing to the main email section before you clicked on New Message. I have to go to the Thunderbird icon on my taskbar then hover over it to see two previews come up, the main email section and the message that I was working on. Then I click the latter. So there are my two annoyances. If anyone else has experienced this and found a solution, it would be with gratitude if you would share that with me. I will add that I have reinstalled Thunderbird and that made no difference at all. I did have the ESR version and it too had the same annoyances as this version, so it did not help for me to change/install versions. Thanks!
