Hi, I need to roll back from Thunderbird 135.0 (Release Channel) to 128.7.0 (Extended Support Release) without losing any data. However, I am receiving a message about creating a new profile due to compatibility reasons. I would like to downgrade while maintaining a seamless experience, ideally with just a few clicks. This Thunderbird e-mail client is used in an operational environment. Could you guide me on how to do this? Alternatively, is there a way to get my add-ons working again on version 135.0? I also find Thunderbird’s handling of add-ons across different versions quite frustrating. The frequent compatibility issues between versions create unnecessary problems. Is there any plan to make this process more flexible in the future? Thanks in advance for your help!
