I have just downloaded Roboform but I am getting an error message saying the extension was disabled and to enable it manually (or words to that effect). By some fluke I found where the extensions were but although some items I expected were there, Roboform was not. Any ideas in a completely non techie way please, as I am pretty much clueless when it comes to fixing anything on new technology, on what I have done wrong or if there is a way to download an extension I am using Safari 10.6.8. TIA
