I noticed yesterday with version 115.4.2 32-bit (I just updated now) that an e-mail, part of a correspondence, would not load. Actually it did load but it seems to have permanently replaced the original message with a completely different e-mail from a different sender. But the From and the Subject lines pertained to the e-mail that was supposed to be there. The replacement message, if it matters, is an e-transfer notification, again, from a completely different sender. I noticed then that a few other e-mails show only code data in the body. This is loading from a Gmail account which appears to be intact when I log in there directly. I was also concerned when I first went to open Thunderbird from the taskbar, that a Win 10 pop-up appeared as I hovered over to click the icon, showing "recent" e-mails from all different dates, most of them well in the past and certainly not accessed recently. This has me concerned about a security breach. PS: When I tried to remove the "recent" e-mails pop-up menu I accidentally deleted the taskbar shortcut and now can't get it back. Well, I can but the TBird icon won't reload and it just shows up as a blank icon.
