Rated 4 out of 5 stars

"Thanks for the review. The pop-up based interface is a main feature of this add-on. . . ."

Yes, it's unusual, but I'm getting comfortable with it; I've moved the button all the way to the left, which minimizes the resizing distractions.

". . . but i understand your wish. I will add an option to switch between tab and pop-up interfaces."

Fabulous! Thank you.

Also, I've been noticing that one or two feeds will "hang" sometimes and not time out, so that the rotating dots (the "working" symbol) on the button remains until Firefox is restarted. Possible bug?

This review is for a previous version of the add-on (1.0.1.1-signed).  This user has a previous review of this add-on.

I just see the loading problem with my brand-new slow Internet connection.
I will add a customizable timeout to solve this problem.
