Internet Explorer runs a distant second to Firefox amongst Lifehacker readers, but IE8 does have a few useful tricks up its sleeve -- including a bunch of add-on tools to make life easier for Facebook addicts.
Microsoft's IEBlog rounds up a bunch of IE8 accelerators and web slices (effectively extensions) designed to make sharing content with Facebook friends easier. There's even a toolbar option if you want to feel all early 2000s while using a modern browser. None look like a reason to switch to IE, but if you've got friends and relatives determined to remain in the Microsoft browser world, they're useful tools to point out.
