Mozilla Developers Testing Mobile OS
MojoKid writes "Mozilla has been experimenting with an interesting idea called Boot 2 Gecko. Essentially, B2G (as it's called) is a mobile operating system based on the Web, as opposed to what the project's wiki calls 'proprietary, single-vendor stacks.' Mozilla has something here. Open Web technologies provide an intriguing platform for lots of things, mobile and otherwise. The B2G project is still pretty new, but according to the project roadmap, testing has already begun and will continue through the rest of 2011. Messaging, telephony, and battery management aspects of the OS are underway, and contacts, screen/power management, and settings are scheduled. A product demo is scheduled for sometime in the first quarter of 2012."
Right now, b2g uses considerably less memory than Android. The difference is about 200mb on the phone I tested on.
Of course, b2g doesn't currently do much, and our memory usage will probably increase as we add more features. But we're paying close attention.
Firefox is slower than chrome, but generally uses less memory. There were a couple versions of FF that had a memory leak problm if I recall.
