I want to use Thunderbird Email app which I have used for many years. Is there a Thunderbird add-on that can remove the bare line feeds before the written E-mails are sent or forwarded? I can send E-mails to myself and forward L.L. Bean and Wild Wings E-mails All others fail because of BLFs errors. This problem only started about 2 weeks ago. I do not want to use a browser based E-mail application. They are clumsy to use.

Thank you.

Try to start Windows 10 in safe mode with networking enabled.

Does the problem go away?

Windows safe mode disables anti-virus software. This is a troubleshooting step, not a solution.
