For a one man crew, This works amazingly well. When I first saw it, I immediately thought it was a scam to get your information. But then I daringly added it with the back up plan of immediately changing my password should anything go awry. Now I can't use FB without it. I wish there was a version for the mobile version of FB. This is my first time using it on Opera. Hopefully it works just as well as it does on Firefox, Brave and Chrome.
