Every time I use Opera I get banner message that says "The extension upgrade requires additional permissions. Go to the extensions manager to accept the upgrade." This poorly designed message does not say which extension requires additional permissions. I cannot keep this annoying banner from coming up. I have even uninstalled or disabled every extension to no avail. Anybody have any ideas?
