FireShot (Great Firefox add-on)

Fireshot is another invaluable Firefox add-on I use all the time. It's basically a screen capture utility that takes a snapshot of whatever is in your browser. It then immediately goes to a quick edit screen that allows you to do minor editing and cropping of the image. Then you can save it or do whatever you want with it.

It's great for blogging, especially when you just need a small part of a page, or something like that. Just click the FireShot toolbar button (just one little old button. Very unobtrusive) and it snaps a picture.

I like tools and add-ons that become transparent in their ease of use and usefulness. It's as easy as click, crop, and save.
