Do you uBlock origin installed?
It should block ads n unnecessary stuff to save some data.
You could filter/block images and audo/video/media(from all websites or some specific websites) if you want to save even more data.
Adding that in your filter list would block all images and media, from all websites. You can adjust it for the specific websites that you want it to affect.
