Needs drag-scroll to achieve its potential Rated 4 out of 5 stars
Works well for checkboxes in the viewable area, but it doesn't scroll when you drag the cursor down or up out of the current viewing area. So if you have a long column of checkboxes, you have to do multiple scroll/select operations instead of one single click-and-drag. If a click-and-drag feature were added, this add-on would be worth 5 stars. Works with FF v9.
