Surely you all know how to do this but just in case, Walt Mossberg tells how to open many web sites at once.
Q: I like to visit about 50 news sites every morning but don’t want an RSS feed only. I like to see the entire site. Is there a way to open all of them at the same time, without having to click on each bookmark one by one?
A: Certainly. All you need to do is switch to a tabbed Web browser, like Firefox or Opera for Windows or Mac; or Safari or Camino, for the Mac only. These browsers can open multiple Web sites, in the same window, marking each site with a tab bearing its name. And they allow users to open these multiple sites with a single click. Though each differs slightly, all have a command — usually called “Open in Tabs” — that will open a list or folder full of bookmarks with one click. For instance, every morning I open about 20 technology-related Web sites in Firefox or Safari with one click.
Internet Explorer 7.0 — available as a beta — also has tabbed browsing.
