Great addon, but... Rated 4 out of 5 stars

I've loved this addon since I discovered it last summer, but now the 4.0 isn't as 'nice' for me. I'd like the option to control the number or popups that display. The older versions were a single popup notifying me that new feeds were in, but now there's a popup for every feed, so at times there are myriads of them escalating one on top of the other...
Also I just had a problem where a popup telling me I had 5 new feeds on BBCNews somehow appeared at the very top-left of my desktop - instead of the usual bottom-right. And it won't go away, even after closing FF; it stuck there. (At least it wasn't an embarrassing one LOL)
I've gone back to version 3.1.6 for now and that belligerent notification popup has now gone away.
I think this would be just about perfect if it gave a bit more control over those options.

This review is for a previous version of the add-on (4.0).
