Upon upgrading to Supernova, 115.11.0 (64-bit) on Kubuntu I can no longer sent any messages to any of my mail servers. All are SMPT; gmail and other commercial servers. The hardware configuration is as follows: KDE Plasma V 5.27.11 KDE Frameworks V. 5.115.0 QT V. 5.15.13 Kernel V 6.6.6-0608-generic (64-bit) Graphics Platform Wayland Intel Processor i7-1260P Thunderbird was working fine prior to the upgrade. There were no crashes nor other sources of data corruption during the upgrade process. The original upgraded version was via snap; I have removed that version and installed the update from the bzip/tar on the Thunderbird site. I have attempted to restore profile data from known good sources with no luck. Thunderbird in --safe-mode still has the same problem. I have traced the issue down to what appears to be the primary error and filed a bug report (bug 1898759) in case I am not unique. NS_ERROR_FAILURE: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIAutoCompleteInput.popup] LoginManagerChild.sys.mjs:149 observe resource://gre/modules/LoginManagerChild.sys.mjs:149 handleEnter chrome://global/content/elements/autocomplete-input.js:573 handleKeyDown chrome://global/content/elements/autocomplete-input.js:538 AutocompleteInput chrome://global/content/elements/autocomplete-input.js:39 Any suggestions for correcting this issue or debugging this issue would be greatly appreciated before I attempt to download the code, build, and debug for myself. Thanks!!!
