Mozilla announced earlier this month that the HTML5-based mobile platform it’s currently concocting will launch in early 2013 as Firefox Mobile OS. The platform will focus on open Web standards, and Mozilla has already partnered with Deutsche Telekom, Etisalat, Smart, Sprint (S), Telecom Italia, Telefonica and Telenor to support the platform. TechWeek Europe recently published a gallery of screenshots depicting various areas of Firefox Mobile and it definitely looks, well, like a familiar mashup of Google’s (GOOG) Android OS and Apple’s (AAPL) iOS software. Considering the two platforms are completely dominating the smartphone space right now — just ask Nokia — we suppose this could be a good path to take in terms of giving users a UI they’ll already be familiar with. As aggressive as companies like Apple are getting with software and design patents, however, Mozilla would definitely be wise to tread lightly.
