"Save Images" does not work correctly with versions of Firefox greater than 48 due to the latest versions of Firefox using multi process functionality. If multi process is disabled, it should work correctly but I cannot guarantee that it will.

Until the developers of Firefox have sorted out all the changes they are making, I will not be updating Save Images.
Trying to upgrade "Save Images" to work now would require losing 80% of is current functionality, which is not worth the effort.
