FireFox leaves the images as is with the ability to increase font size (like explorer) but without changing image size so the webpage still looks as is
Images in FireFox open resized already..
Well I like FireFox, especially the Tabs features, where you can open more than one page in the same window, but as ragnar said, it doesn't load faster, but it shows what it loaded already, that's one of the good things in it, but it also bores u while waiting for the rest of the page to open
