I have followed all the instructions to install instapy onto my raspberry pi zero w and i get this error:

Not sure if you are still with this.. but I had the same problem and it seems raspberry pi zero w cannot run Firefox ESR (or at least I couldn't make it work). As I understood, it is something related to Firefox being build for ARMv7 processors, and Zero it's ARMv6.
Again, I'm not sure what I'm saying is correct, but I switched to the Raspberry Pi 3 B+ and everything works fine now
