Are you sure it is 62. The release is in the 50s and 60 is stable any currently being rolled out.

Matt, I have 60.0. Wrote 62 by mistake. Corrected. Two other problems: 1. Clicking on "Preferences" brings up an empty box. 2. Clicking on "Email link" in Firefox brings up an empty e-mail.

hold the shift key and start Thunderbird. It works to put it in safe mode in windows, I assume it works in Linux.

same issues in safe mode?

Thank you. Having the Shift key pressed when starting TB makes no difference to the three problems which I described.

There is no indication that TB is running in safe mode.

I might say that no add-on is active.

help menu > restart with add-on disabled. Gets to the same place and it does do other things other than just add-ons.

Thank you. When I did that, things began to work. Do I now completely remove add-ons? How do I deal with "other things"?

It seems that an incompatible add-on named CompactHeader was the cause of the problem. Thank you.

Do you still have issues if you reinstall it. It is not as if that add-on does anything with the message display to cause the problem you mention.

TB is running well, thank you. I cannot help in identifying the cause of the problems.
