What is Save-Data: on?
'Save-Data: on' is a Firefox add-on that works by sending the 'Save-Data: on' HTTP header with every request. It informs websites to minimize data usage, potentially leading to lower quality images and fewer media elements on webpages. Note that it is not a data compression proxy like some modes in other browsers.
