I've downloaded trial version of ESET Smart Security Premium and I'm thinking about buying the license, but I have a problem with password manager extension, it cannot be installed on Opera browser, it keeps showing error, though it says that Opera 15+ is supported. I tried installing it through "install Chrome extensions", but the add-on doesn't register the Password Manager program as if it hasn't been installed on my pc. The version of Opera that I'm using is 60.0.3255.84. Is there any way to fix this?
