It's light, but annoying to use.
It can save pictures in JPG or PNG formats.
But: You have to click the little icon in the addon-bar (bottom right), then navigate through the context-menus to reach the correct way to save the file.
There is no way to save a page on one-click.
Also, if there is any space-symbol in the website title, the file will also be named with those space-symbols but the Add-On can't handle spaces in the name and therefore you need to rename the file before saving - EACH TIME!
Nothing for me.
