I can't figure out how to use it. I had Price Blink, which now directs me here. I click on add on to Firefox. I get this page, a whole lot of advertising, but no place to actually install this. And every time I so much as look at a page of items to sell, Price Blink pops up and redirects me here. I feel like I fell into a dryer -- I keep going around, with no way out and nothing accomplished.
