I continually get this prompt:

I don't care that I can't access the Calendar. What I do care about is this annoying prompt. Is there any way to keep it from occurring?

For the record, I use the Waterfox browser. It's pretty much the same as Firefox so rather surprising that it isn't supported, but again, I don't care. I don't need the calendar . . .and don't need this continual prompt. grrr

Thanks!
