I am running ver 128.5.2 esr 64 bit on Windows 11. When I open Tbird, it takes at least 2 minutes to load messages. When i do as mass delete, it goes really slow also. I get a repetition of numerous mail titles across the top of the page when the messages are finally loaded, and they are old messages. How do I get rid of them? All of this has happened after the new version of Tbird was installed. Previously, everything I mentioned above was very fast.
