My Thunderbird just did an auto update and now the new update screen does not show Thunderbird at the top of the page or the usual About options or reinstall a previous version. I lost all of my important folders and my 3 email accounts with their folders. What happened? And, how do I get them back. I cannot even tell what version of this Thunderbird I have now !!!!! The image below is what my new Thunderbird page looks like. :(
