I use FireFoc 35.0, but cone to think of it, I have had some download failures using older versions of FireFox too, so you may be right about that.
I'll go back and try again with IE-11, though I really don't normally use it for much, having had problems getting Microsoft to fix things in the past.
My booboo, I tried again, with IE-11, and the file downloaded just fine.
Guess I need to put a PostNote message to myself to remember that if all else fails, try IE-11 to see if it works?
Come to think of it, I did leave Bugzilla Report about this for Mozilla, some time ago, so guess I should be bugging them about fixing it instead.
Thanks for the reminder, I won't blame anyone but Mozillla about his again.
