How t remove strange artefect which appeared in UI
I've had Thunderbird instaled on this Windows 10 machine for about 18 months, and it has been running fine.
A couple of days ago, a strange grey bar appeared along the bottom of the Thunderbird window, with red test "toolbarbutton" - see screen shot. I am not sure why this suddenly appeared, there were no unusual events at the time. It just showed up, one day.
Any suggestions how I can remove this extraneous artefact. I tried a lot of add/remove toolbar, change layout, etc, through the View menu, nothing made any difference. I also trawled through prefs.js but didn't see anything obvious.
Very grateful for any assistance.

have you tried restarting without add-on from the help menu? My guess is it is a poorly behaved add-on that is causing the issue. IF the restart works, then it is time to work out which is the issue.
