I can't seem to reproduce it?
As I can see from the attached pictures, the problem was on my side. What about downloading the filmography, does it download it on the first attempt for a specific person or do I have to run the script again for the same person to download the filmography. In most cases, for me, the filmography download is successful only on the second attempt, which means that my modified firefox selenium_script-People_4_pages_v3.2 is not fully compatible with the script. My selenium script will need to be fixed.
