I lost my Profile/Mail on update to Thunderbird 68.

If this is you,  then you are not alone.  Thunderbird 68 comes with this fancy new profile per install thing that the Firefox folk invented with Firefox 67.  It serves a purpose,  but for the vast majority of users it is nothing but a nuisance that offers yet another reason for things to go wrong.  But it can be beaten and once set should remain the same basically forever.  The current issues are mostly about changing from 32 to 64 bit builds and once that is done should not have to be repeated.

In my instruction I assume that the profile is located in the default location.  if you changed this default to some other drive for space reasons for example,  you will need to correct my instructions so your looking in the right place for your old profile.

First navigate to the Troubleshooting information on the help menu. Scroll to the bottom of the "Application Basics" information and select the last entry.  About:profiles.



 This will open a new tab showing the about profiles information.


This heading is followed by all the registered profiles Thunderbird currently has registered. 

If you have more than the current default profile listed,  it is worth noting the name of the current default and clicking the "Launch profile in a new browser" button for other profiles shown.  The label is incorrect and awaits correction.  But clicking the button will launch Thunderbird in a new window with the selected profile loaded.  If it happens to be what you are looking for.  Click the Set as default button and you good to restart.

If none of the profiles listed here are your missing one,   you will need to move on to creating a new profile that is in the same location as the old profile.  Use the "Create a new profile" button at the top of the about:profiles page to start Thunderbirds Create profile wizard.


The action here is to use the Create profile button. This will open a Create profile Wizard dialog.

Lots of information here, but just click Next.


 This dialog is upset because the name already exists,  as does the location,  so change the name.  To anything.  Something like OldProfile or MyProfile might be a good easy name to remember if you ever have issues in the future.

Now click the choose folder button.  This will open a standard open dialog in the default location of the profiles.  What I see looks like this
This list of files with their random characters and "profile names" on the end is the same list as shown in the about:profiles page.  But there should be one more profile listed here than is shown in the about:profiles page.  Select it as the location for your new profile and click ok.  Then in the profile wizard click finish.

You will be returned to the about profiles page and the list will be refreshed with your new profile name which will show as default. A restart of Thunderbird should see the correct profile launched.
