Thank you to AlwaysSAI and Ms_Gwyn for your helpful advice. It worked! The blocker is still there, but the scanner is working.

Gwyn, I should have called you as soon as I had problems. (She installed Fire Fox on my computer a few weeks ago…you should have seen her fingers fly! I was like, “what
are you doing?” She’s amazing.)
AlwaysSAI, I’d say you bear a very tiny resemblance to Bettie Page.

You’re not into leopard-skin bikinis or bondage…….er, nevermind. None of my business.
Well, Jess, my clothes were definitely all wrong and I’m sure yours were perfect. I liked “preppy”; I just didn’t know how to pull it off. My favorite outfit in high school was white hospital pants with the cuffs twisted and folded up, a torn white t-shirt with silver paint splattered on it, white bobby socks and keds, and a huge white bow in my hair. Passable in L.A. – completely out of place in Maryland.
I’ll be back real soon.
