Nobody knows a solution?

tufuzay: I don't want to torture anyone with Chrome.

zalex108: That's the same thing I did, but I need to disable any temporary changes during the session as well.

Hello.

I would like to know how I can disable changing the settings in Opera. I have found out that the settings are saved in C:\Users\username\AppData\Roaming\Opera Software\Opera Stable\preferences. If I make this file read-only, the settings will always go back to its previous state when I re-start Opera, but I can still change the settings for the current session (seems like the temporary settings are saved into a different file somewhere). I would like to block changing the settings completely and at all times. Is this possible in any way?

Thank you in advance for your help.
