I got a technical complaint from a reader about troubles he was having with "Firefox" and reading the other comments before posting a response.
I have to plead total ignorance to what Firefox is. I'm sorry.
When I write a comment in response, the message box is about two inches wide by four inches wide, and I have difficulty reading it myself. If I plan on a detailed response, I open up another window so that I can review the comments in one, and respond to them on another.
I don't know how to fix it, but I will gladly take any technical advice.
