Works fine in Firefox Portable** Rated 5 out of 5 stars
I used to use this some--always worked well. Now I'm looking for something to use instead of Google Reader for all of my feeds: I think this works/looks even better now than it used. (**I don't know about other portable versions of Firefox, but it works fine in the one from PortableApps.com.)This review is for a previous version of the add-on (188.8.131.52-signed).
