Great, it wokrs! There are still little errors after starting the browser ( visible only in terminal ), but this is not significantly for me now. Only for info, maybe it is not so difficult to repair it:
Code:
[3391:3391:1616469448:ERROR:chrome/browser/extensions/extension_prefs.cc(728)] Bad or missing pref 'state' for extension 'ahfgeienlihckogmohjhadlkjgocpleb'
[3391:3403:1616494309:ERROR:chrome/browser/webdata/web_data_service.cc(579)] Cannot initialize the web database: 2
I just made a symbolic link /usr/bin/google-chrome, that refers to /opt/google/chrome/google-chrome. I hope, that was a good way to do it.
As I said, I am happy, that I have my favorite browser back. So thank you very much for your time and help.
Kind regards,
Fico
