OpenSUSE :: Failure Migrating Firefox And Thunderbird From 11.2 To 11.3

get my system from 11.2 to 11.3, I made a clean, new install instead of an upgrade. (I also used the opportunity to change to a new, bigger harddrive.) I installed Mozilla Thunderbird from the repositories and (using the root account) tried to replace the automatic entry in .thunderbird with my own cryptic-named folder which I copied in from external storage. I changed the target name in the profiles.ini to my folder's name. (I also made sure that although "root" did the copying, my main user is still the owner of all folders and files.)Same procedure for Firefox (except for the installation part).

I made the same kind of copying for the OpenOffice "user"-folder and Office came up with all my individual settings. But both Firefox and Thunderbird gave a failure notice, telling that "the program is already running, but does not react. In order to open a new window, you need to shutdown the existing process or restart your computer."(Original German: "Thunderbird wird bereits ausgefhrt, reagiert aber nicht. Um ein neues Fenster �ffnen zu k�nnen, m�ssen Sie zuerst den bestehenden Thunderbird-Prozess beenden oder ihren Computer neu starten.")

I restarted the computer several times, but to no avail. (A similar (or the same) bug was reported two years ago, but it seems that no solution was reached [see ]Thunderbird l��t sich nicht mehr starten - linuxforen.de -- User helfen Usern.)
