I had to reinstall my Windows 10 and I reinstalled Thunderbird 68.10.0 The emails are as they should be but I can not select a @Sender column I received an email from somebody I knew had dies and it had been spammed But the is no way to see the Actual email without opening the email. I received an email which says it's from ymail.com The header shows "[email protected]" But I can only see this after opening the email My wife also has Thunderbird 68 on her computer and the @ Sender column is visible But not on my computer How do I restore it Peter
