I forgot to add that everything about the agenda is gone : no more "Events and Tasks" menu, no more icon, no more agenda tab in Options, and the Lighning extension refuses to install... Incompatibility due to the last TB upgrade ? Any explanation ? Thanks if you can let me know why ! Back to Google calendar via browser :-( All the calendars used in my TB agenda are imported from Google Calendar, and I have been used them with no problem for years... Thank you.

For TB 52.2, I believe you will need Lightning 5.4.2, and the only source I can find is here (for Windows).

For example, this is the installer for the EN-US version.
