Lately when I delete an email from one of my addresses (not the other), it takes 8 to 10 seconds to delete. During this time, nothing else works at all.

I have two email addresses that come into Thunderbird. The one deletes emails fine, but on the gmail address one, I cannot delete emails efficiently. First it was 6 seconds wait and now it is up to about 10 seconds. During that 10 seconds, no other action can be taken. The message at the top reads, "Thunderbird is not responding." It does not happen every time, once in about 10 emails or so, I can delete and the message is immediately deleted. What is going on?


Also I cannot delete messages from my "Sent" email folder. There are 5000 in there and Thunderbird will delete about 10 of those at a time and very slowly. Takes a long time......then I can delete about 10 more maybe. I was able to delete my trash very speedily a couple days ago, no problem with that.

Do you get a 'Not responding' notification in the title bar?

What is your anti-virus software?

As I said "At the top it says Thunderbird is not responding." My anti'virus software is Windows Defender Security System. Help. Nothing is working.

I have tried to answer this question 3 times - it just escapes!

Try to start Windows in safe mode with networking enabled. - Win10 https://support.microsoft.com/en-us/help/12376/windows-10-start-your-pc-in-safe-mode

Still in Windows safe mode, start Thunderbird in safe mode. - https://support.mozilla.org/kb/safe-mode

Does the problem go away?

I do not know what you mean or how to do that???? Do I close down the computer completely and then power up and put that website address in the Internet Explorer google spot? You are talking computerese and I can't follow. My son, who is a cyber security guy, worked on this a lot and he couldn't figure out the problem. He was astounded at the "Help" for Thunderbird.

Follow the instructions in the linked articles. Or better yet, ask your son again.
