This seems to work best on websites that aren't super popular, but those for those it works really well. Sometimes you get weird duplicate listings that are only a few KB apiece, but I think that may have more to do with how the sites loads than with any shortcoming in the plugin.

Unfortunately, about half the time when you click "Download" next to a video, nothing happens. You don't get a prompt for a location to save, nor any indication that the plugin is actually doing anything. When it works it's great, but lately that's been the case roughly half the time.
