This is a great little add on for Firefox. You can right click and drag a selection over any links in a page and it will open all the links in a new tab or a new window, all at once, depending how you set it up under the options button. It's great for sweeps like classic heartland, woman's day, intouch weekly  or where there are a bunch of sweeps listed on one page.

I had upgraded to firefox 3.01 and it wasn't working but I found someone had posted a link to a version of snap links on their blog that does work in firefox 3. This is the version I'm using and it works great.

I hope this helps somebody.
