Assuming you are currently running Thunderbird version 60.5.2

If the above info on reinstalling Thunderbird 60.5.2 does not work for you then..... As this is an important thing which you are probably using a lot, I suggest you uninstall the Thunderbird program via Control Panel > Program and Features select Thunderbird and click on 'uninstall'.

Then download a fresh install for previous version and report back on whether this works ok.

then choose prefered language Download the file, run and install.

Perhaps you should post your issue in the bug report. The developers think they have it fixed with reinstalling from Thunderbird.net. If that is not working, please advise them.
