Great as BBC iPlayer is, I like many mac users had struggled when using Firefox to download programmes. For some reason, after each download I was prompted to install the iPlayer desktop application again, but in doing so was still only able to download a single programme before being stick in the loop again.
The work round for me was to install Google Chrome which works fine although this is a ‘clunky’ solution as I still use Firefox for my main browser – Google adoption has to stop somewhere!
