My previous post seems to have disappeared, so will try again. I am 85 years old and have been using Thunderbird fo over 15 years with out any problems. Afew days ago I tried to send an e-mail and didn't have any "Send" button. In trying fix, I some how deleted my contacts sidebar. I sill have my addresses book. I have tried everything to retrieve them but no luck. I tried removing Thunderbird and reinstall, but it comes back the same. I would appreciate an guidance in trying to resolve my problem. Thank You
