I see to have found a workaround: ubuntu@friendly:/usr/bin$ ./thunderbird -allow-downgrade
Users shouldn't need to manually run this. Chatter from the below Web pages says: mahmacc said: > The instruction to change to the Thunderbird installation directory and then > run the command as ./thunderbird.... is not necessary for Linux users whose > paths are set up so the command above will work.)

Use this profile only with that newer version, or create a new profile for this installation of Thunderbird. Creating a new profile requires setting up your accounts, calendars and add-ons again."
