The latest simulator for the upcoming Firefox mobile OS is aimed to please developers planning to sell applications.
The simulator is a test environment for the forthcoming Firefox OS, a Linux-based OS for mobile devices designed with tight integration with the Internet using open web standards such HTML5.
The first devices came on the market earlier this month in Spain from operator Telefonica, with Deutsche Telekom in Poland due to release devices soon. Firefox OS is a new challenger in a market dominated by Android and iOS phones and is seeking to compete with high performance, lower-cost phones.
The simulator's latest integration lets developers test how receipts are delivered for their applications from Mozilla's Marketplace, where applications for the mobile OS will be sold.
"This way you can test receipt verification with the various types of receipts that you may require -- valid, invalid, and refunded," Fabbro wrote.
Mozilla has also added a feature that lets developers use a style editor tool that can apply CSS (Cascading Style Sheets) changes immediately to an application when using pre-build version of the Firefox browser.
