I find this addon pretty useful, another cross browser, cross device way is to use http://www.multiopen.net You can save up to 15 links as a package and then open all of them at once with a single click in firefox, chrome, opera, whatever. As long as you save the resulting id, you can use it anywhere. Its kinda like jsfiddle but for the specific purpose of opening multiple links at once. I Use it every day to read the 7 or 8 sites I always check.
