A very BUGGY addon Rated 1 out of 5 stars
My firefox is 15.0b1.
If you make the mistake of using this guy's addon, then try to customize firefox's UI/GUI, your UI/GUI gets robbed of almost everything. I already posted a 1-star review of this addon for both that reason, & because this guy NEW about this bug (from another person's review of it), but has not FIXED it. Maybe it would be fixed if this guy would spend less time SNIPING at people for complaining about this addon. Now, my earlier review is gone, so here it is re-loaded.
For those of you who want some GOOD video downloaders, use ALL of these instead.
