Hi, The last month or so, probably after uninstall Bitdefender and using MS Defender, Thunderbird has become very slow in response. When tyoing a new email, it can take up to 5 seconds from typing to the letter appears in the mail. And toggling between mails can also take many seconds.

What can I do? The software is fully opdated, windows 11 on a modern Lenovo ThinkCentre with plenty of RAM.

Best regards
