Fireclip is a pretty interesting Firefox add-on. It allows you to select and save part of a website, say a weather report, a web comic or anything else that you can think of, and load the saved part later to see if there have been any updates to it.
This means you can check for web updates without having to visit the actual website. It’s a bit like RSS News Feeds but more flexible since you can select any element on the website and monitor that one.
The add-on adds a sidebar to Firefox which displays all the currently saved elements and provides buttons to add new clips. Adding a new clip is simple. Click on the Select Clip button, you will notice that the add-on automatically marks elements on the website when you move the cursor around.

You click once to select that element and have then the opportunity to fine tune the surrounding box by using the arrows to change its size.
Once it is in the sidebar you can open it in the gallery. The gallery also contains a link to the websites that you got the clip from in case you want to visit that website as well. The biggest benefit of Fireclip is that everything is stored locally without having to signup at a website that stores your data.
