Rated 5 out of 5 stars

Absolutely greatissimo! I'm on a site with basically one main page that has, get this, a little less than 8000 subpages. Obviously everything would crash if I tried to open them simultaneously, and I don't have the need to, but with this I can open, say, 15 pages at a time and duly stay sane by saving my mouse arm and nerves. Many thanks!
