Qualcomm announced today that it’s working with Mozilla to bring a compatible version of Firefox to Snapdragon-powered Windows computers. The new 64-bit version of Firefox will be optimized to run on these computers for better performance.

Firefox is making each browser tab run on individual cores in the CPU and Qualcomm, which has announced the eight-core Snapdragon 8cx earlier today, will have plenty of cores to spare. There are few additional details available; we’ve reached out to Mozilla for further information.
