Works but buggy Rated 3 out of 5 stars
when I use this addon, on restarting FF, I find it has 'removed' itself from the addon bar and the preferences box is unavailable. I have to reinstall it for it to be accessible again. *Sometimes* but not always, restarting FF will make the addon available again, but you cannot do that if you have started downloading. Its a good job you can reinstall without restarting FF.
It seems to work on my FF15.0.1 ok apart from this bug.
