Jumping pages wastes time. You know, like when you see a link you want to send to a pal, you have to copy the link, open a new tab, sign into your email, paste the link, etc. You jump from one page to another, hence page jumping. So if you're the type to send a lot of links (and are a Firefox user) you may want to check out the Email This add-on.
Email This allows you to highlight the text you want to send, click the toolbar button on your browser, then from a pop-up window, Email This will automatically populate the title, address, and highlighted text into a message so you can send your link and be on your way without leaving your page. It's saved me quite a bit of time, since I love sending links. I bet you would have never guessed that about me, right?
