How make Safari always download CSV files instead of opening them in-page?
I have the same issue and have done some web searching and have not found a good answer.  This does work consistently for me in Chrome so when I need to export a CSV, I just do it in Chrome.  I have been able to cut/paste the Safari text into TextEdit, switch it to "text only" formatting and then save the file as a CSV, but this is so clicky -- if I'm going to do it more than once or twice, I just switch to Chrome for that browser session.
