I have an issue with Vivaldi not being able to store passwords or cookies. The issue appeared after I decided to experiment and install KDE Plasma over Gnome
Not sure if it is relevant, but I have disabled KDE Wallet as it constantly asked for passwords during the Vivaldi startup

Can you please let me know what direction to look at?
Thank you.
