You need to add a feed for it to appear in GrabMyBooks. To do so just enter the feed url in the text field on top of the screen.
Validate by clicking on the Add Feed button.
Once the feed has been added a confirmation message is displayed.
The feed appears on the left side of the screen in the feed list.
You can add as many feeds as you want. The feeds are saved so that next time firefox is started they will be shown in the feeds screen.
Visualizing a feed
By clicking on the feed name, its entries are shown. By clicking on an entry, a description of its content appears on the right side of the screen. Note that this description is not the article itself, it's just a few lines about it. GrabMyBooks will grab the full content.
A feed can be refreshed by clicking on the refresh button. Any new entry will appear.
The visit button opens the entry page in a new tab in case of you want to see the content on its actual website.

Grabbing feed content
For each feed entry worth being part of your book, select it by clicking on the checkbox beside it.
Then when you are done with your selection add it to the book by clicking on the Add Selection To Book button.
A message appears showing you the progression of the grabbing operation. If there is something wrong, for example an impossibility to connect to a feed page you can cancel the operation by clicking on the Cancel button.
Once all selected feeds have been added to the book a notification message appears on the right of the screen.
On this notification window, you can control if the feed entries have been added correctly. You can delete one article or the whole added set.
