When you start with Profile Manager and select your working profile, is the box "Use the selected profile..." checked (see picture)?

If i start with the ProfileManager and i select my profile, all works fine! Without ProfileManager, every start, Thunderbird creates a new profile.

A reinstall of Thunderbird did not solve the problem!

Yes of course the checkbox is selected!

Then the Thunderbird start with the selected profile. After a restart, Thunderbird create a new default profile. Every start a new one.

With the Profile Manager i can delete this new profiles and can select my Profile.

Are you running TB from the downloaded dmg file or did you move the file to the Applications folder? Settings aren't preserved unless you do the latter.

I have regular installed Thunderbird on my MacBook Pro and use it since 10 years without problems! The problem occour since a update in the past but i don't know exactly the version. The update i make over the integrated update and i am on the release channel.

I never think about that a application can bes started in the openden *.dmg file ;-)
