I just migrated my thunderbird profile to a new computer. In thunderbird, Iuse the classic view with acounts and folders on the left, message list in the upper right, message text in the lower right. I have two POP3 accounts, three IMAP accounts, one news account. After copying the contents of my old profile onto the new machine, initially the number of unread messages was not displayed (at least for the POP3 acounts). All folders looked as if they did not have unread messages. When starting thunderbird, scrolling the left window (i.e. the one with the accounts and their folders) was very slow. Thunderbird would not react for nearly a second. The problem was worse when the POP3 accounts were in view, and was not there when the news account was scrolled into view. Restarting thunderbird did not help. When I clicked individual folders, the number of unread messages showed up next to the folder names. And scrolling got faster. After clicking all individual folders and subfolders in all accounts, scrolling speed now seems back to normal.
