Thanks Matt for your reply, I could not find troubleshooting and my 3 line logo at top right of page..has no help nor troubleshooting.. I love Thunderbird... I'm 77,,, no longer travel and building pretty stationery from ground up is my savior to eat up my days... No other program does this for me.. None are as equal...

I have deleted the program and reinstalled but didn't help.. I have found gmail is fine... so it is my Thunderbird...

Any more suggestions... You know some grandmothers have a gifted computer person in the family... I am the GIFTED one in my family...and always helping the friends and family fix their computers...

Have a good day... thanks, Jomilt

Just curious, what prevented you from finding the Troubleshooting Information based on Matt's instructions at https://support.mozilla.org/en-US/questions/1112106#answer-849802 ?

Matt did a good job... I clicked the 3 line logo here on this website and other places...but not ON MY THUNDERBIRD PROGRAM. That was my fault. He is not at fault... just this old lady!!

Thanks Christi for trying again!! I surely needed help drastically!!

Thank you Christi and Matt.,... Y'all earned "angel wings" with your help!!

Have a good day. Jomilt
