Test Pilot is Mozilla’s program for experimenting with some of its more outlandish ideas for Firefox and beyond. Some of those experiments make it into the browser itself, some become stand-alone extensions and others get unceremoniously canned. Today, the organization is announcing two new Test Pilot projects: Price Wise, which lets you track the price of items in online stores, and Email Tabs, a tool for making it easier to send links to people by email.

Price Wise is a pretty self-explanatory service. It works for Best By, eBay, Amazon, Walmart and Home Depot and lets you track price changes right in Firefox. That’s obviously not a novel idea. Plenty of other extensions do the same. Still, it’s nice to see a tool like this from a relatively neutral source. Mozilla tells me that all of the work happens on the user’s machine and that all of the development was done in-house, without relying on third-party tools. Mozilla also notes that it’s not monetizing this service through affiliate links.
