Vivaldi and Avast Passwords 1.1.2673
As a program part of Avast Antivirus is "Avast Passwords 1.1.2673"
An extension for Chrome and Firefox. Under "Extension" it is also active. But when clicking the key in the menu bar I receive the message: "Extension is not activated"
Excuse me for my imperfect English.
Regards and thanks for answers
May be it is incompatible. But i dont have Avast.
Without any guarantee: May you try a installation of 1.7 Snapshot? Perhaps that works.
Otherwise you should report the bug to Avast so they can test their extension.
