Suddenly, the conversation view has disappeared from my Thunderbird. This happened in version 128, and I have now updated it to the latest version, 138.0.2, but the problem persists. Previously, if I selected any message and right-clicked, there was a local menu option 'View as conversation' (or something similar - I use a localised version). Now, if I right-click the message, it opens with only two options: 'Open in a new pane' or 'Open in a new window'. No conversation view. The default shortcut (CTRL + SHIFT + O) does not work either.
(I did not change any settings, I only compacted folders and tried to rebuild thir index because the global search did not find existing messages.)
Any help on how to restore this functionality would be very much appreciated! Thanks
