Windows/Mac/Linux (Firefox): Flight-tracking website Yapta, previously mentioned here when it was an Internet Explorer-only extension, has released a Firefox version of its tagging tool. The same principle applies—head to an airline or travel aggregation website, start the standard date/passengers form rolling, and then click the "Tag it with Yapta" button on any flights you want to watch.

Yapta is a free download, which requires a sign-up at Yapta's website to function, and it works wherever Firefox does
