Ask HN: for feedback on the product we just launched - a Firefox addon

This is the product I've been working on for a few months now. The company I work for have a small but knowledgeable dev team, and we really think this product is going to be a useful tool for our audience. We're also pretty convinced it's not been done before. I'd like you to install it and let us know if you have any suggestions, bugs, ideas etc. We've "soft-launched" today to an invited audience, and I'd like to get feedback from fellow hackers before we do the full-on launch. Many thanks for your time. Market: UK Horse Racing Gamblers Scenario: You want to find the best price for a horse that you've just read about. Problem: You have to open a new tab, find an odds comparison service, type the horse name in and compare odds from there. Or you have to open a bunch of bookmakers pages and compare odds from there - a lot of effort. Solution: Odds Anywhere - a firefox add-on (IE coming soon) scans pages you're looking at and highlights horses that are running soon. When you hover, a bubble appears with the best odds for that horse. Homepage: http://www.oddsanywhere.com/ - there's a live demo of the bubble on there. Add-on: https://addons.mozilla.org/en-US/firefox/addon/241026/ - if you want to see it working on other pages. PS: I'm really sorry about the EULA, our boss insisted on filling it with ugly scary stuff :(
