At this moment, don't use it Rated 1 out of 5 stars

In my humble opinion this add-on sucks. There are a lot of feeds which give errors with Newsfox:
downloadsquad, make magazine and so on...
Besides that, images are not automatically visible.

This review is for a previous version of the add-on (0.8.4). 

Huh?

http://www.downloadsquad.com/rss.xml works fine(when valid, which is definitely not always).
http://blog.makezine.com/index.xml works fine.
