When I downloaded the latest update it corrupted my inbox and I lost the content of every email in my inbox prior to that date (7/6/16), how do I fix?
I downloaded an update on 7/6/16 and immediately lost the content of every email in the inbox prior to that date. They are still showing in the inbox but when I open them they have no content. Has anyone experienced this problem? Any ideas on how to get my message content back?

This has got nothing to do with the update.
It sounds like your mail files are corrupted. First of all create a backup of your Thunderbird profile folder. https://support.mozilla.org/kb/profiles-tb#w_backing-up-a-profile
Then try to rebuild the index file of the troubled folder. Right-click the folder - Properties - Repair Folder
Note: depending on the corruption this may erase messages from the affected folder which cannot be recovered anymore. In that case you'd need to restore them from a recent backup done prior to the corruption.
Corruption is often caused by anti-virus software messing with Thunderbird mail files. It is therefore recommended to create an exception for the Thunderbird profile folder, so that the real-time scanner won't attempt to scan the profile with your mail.
