I just got the newest version of Mozilla’s Firefox. When updating it on my laptop, I started exploring Firefox’s add-on offerings and discovered the coolest new tool! The company Cooliris created Previews which lets you actually preview your links without clicking through. It is a huge help when trying to scan tons of blogs for class. I just put my pointer over the link on my blogroll and I can see that site in a second window. I can even play videos and look at photos in the preview window. I am totally sold!
