Slow downloads, poor performance, sux up most of my CPU Rated 1 out of 5 stars

The more I use this addon, the less I like. It is a 3 pane RSS reader, but it is super slow in downloading feeds, suck up 90% of a CPU on a dual core system, and randomly seems to hang or get "busy" doing something. I am using 1.0.3.1 version, but have to suggest maybe some other RSS reader may be a better choice. If this thing had the functionality of Mozilla Thunderbird so that articles could be cached locally, and speed of access & download was fast, it would be a much better product. Look elsewhere.

This review is for a previous version of the add-on (1.0.3.1).
