Research and Productivity Enhancer Rated 5 out of 5 stars
Scrapbook Plus is one of my most favourite addons - indeed, I have used it now for three or four years.
If you have read the description of this addon, you will see that it is like a real scrapbook - you paste into it bits and pieces of anything you find so that you can return to it later. This addon does just that. You save bits and pieces of the web - onto your own computer - so that even if the web page goes away, you still have your scraps saved up, and can reference them any time.
A feature that makes it even more invaluable is this: not only can you save a static version of the web-page, but you can EDIT the page, remove parts you don't like, as well as add notes and highlights, too. This is invaluable if you are doing some intensive study. And if you have several "scraps", you can easily combine them into one. If you know html, you can even edit the html yourself in a text editor and do whatever you want with your scraps.
Another great feature that I put to use is the ability to have multiple scrapbooks - one for this topic, one for that topic.
Scapbook is one of the addons that I cannnot live without.
Before I leave off with my review, I want to relate another context where this addon has really made a difference for me. At one time I could not have internet access at my desk, but had to go to a common computer room for online research. I browsed the net and captured the things I wanted into Scrapbook (using Firefox Portable!) and then came back to my offline desk and dealt with what I found. This addon made such a difference - I spent a small amount of time online getting information, and the rest of the time studying and highlighting my notes.
Thank you, haselnuss!
