Track Airfares in Your Web Browser with Yapta

Remember Yapta, the site that helps you get a refund on airfare if the rate drops after you buy your tickets? There's a new Firefox-compatible version of the service's browser plug-in (previously Internet Explorer-only), which lets you "tag" flights you want to monitor. Here's how it works:

Yapta's Firefox add-on enables you to easily comparison shop for the best fares on airline websites. When conducting a search for flights on a Yapta-supported website, a sidebar notepad will intelligently open to display the My Trips list. Each flight you tag will be added to the sidebar notepad, and Yapta will begin tracking prices.
