Hello everyone, I am in despair. Since few months now, Thunderbird became very slow and it is blocking me more and more in everyday life, particularly with my yahoo account. I have the latest version installed 128.4.3 and work on WIN 11 PRO. Alla the time, thunderbird in blocked and the message "Thunderbird is not responding" appears and it takes very long until I can use it (several minutes). Beside, I installed OUTLOOK, to check if it was coming from my email server but it works fine on OUTLOOK, so my guess is that the problem comes from THUNDERBIRD. Does anybody has some intel on this kind of problem and how to solve it? Thank you in advance for your support and have a great day. Kind regards. Sylvain from France
