Thunderbird changed over night, and is VERY jacked up... none of my inboxes have anything in them, and one of my Email addresses and folder don't exist!!! I received a response from my earlier rant


Try the following:

Set this setting:

   'View' > 'Folders' > 'All' 

Then do this:

   Menu icon > Help > More Troubleshooting Information
   Under 'Application Basics' - half way is Profile Folders - click on 'Open Folder' 

window opens showing contents of your profile name folder

   Exit Thunderbird now - this is important 

Scroll down and delete the following files:

   folderCache.json
   folderTree.json
   virtualFolders.dat
   session.json
   xulstore.json 

Click on 'Mail' folder

   delete 'smart mailboxes' folder 

(do not worry if it does not exist - it just means you have never used Unified)

Start Thunderbird.

Please Report back on results.


BUT IM ON A MAC....SO I NEED HELP IN MY SYSTEM TO GET THIS STRAIGHTENED OUT....OR I PREFER TO GO BACK TO THE OLD PLATFORM....THAT WASN'T BROKE!!!

Well if you want operating system specific answers, it is generally a good idea to mention that you are using something that is not the market leader. (windows has well over 90% market share for Thunderbird)

However, and this is important. I have no idea why you are not able to follow these instructions. You see I don't use apple products. Perhaps you do not have a help menu. I thought such was common to all operating systems.

I suggest you go back to your original rant and ask the responder for clarification. As this is a duplication, or a continuation of https://support.mozilla.org/en-US/questions/1392047 I am closing this topic.
