Does Firefox have a good way to see how big a page is with all the images and other media that are embedded in it? I know about the Page Info button, but i think that only tells me the size of the page’s HTML file and loaded media separately. As far as i can tell, it doesn’t measure external CSS at all. And the numbers it does give me for my own site are different from the numbers i see from my computer’s file browser on my local backup of my website. So is there a good way to know how big a page i visit is?
