ELinks!

As The\_Guest says, it's a text-based web browser (based on the older and less user-friendly Lynx browser,) which I use for FB and other interactives because **A.** it doesn't clutter up whatever session I've got going on my normal browser, **B.** these sites are entirely text anyway and images are nonessential, and **C.** it's extremely lightweight and fast, which was important when I was mostly reading on my Nintendo DS with DSLinux some years ago, and I've just been in the habit ever since.
