Hello, I had been using Thunderbird as my email App for very long time. About a few years ago I stopped using it, due to some annoying errors. I installed the new version a few days ago, however I am some issues: 1. I want to change the default email composing font type and font color. I made changes in the setting and config editor as well. When I start creating an email the font type and color shown is correct. However, as soon as I start typing the default takes over. 2. I have about 50, 000 emails, which I keep for references (ATT-Yahoo). Every evening all the messages disappear, except for about 2000. Then, in the mornings, I have to restart the app and it starts to download "AGAIN". Please advise. Surendra
