The next version of Firefox, currently in Alpha 2, has some fabulous new features, including integrated video support (HTML 5) and presumably audio as well. We need to get working with this to do some bug reporting and find out how it can help us avoid (e.g.) Flash in future. I've got it installed on a VM, because it's pretty unstable, and doing that involved updating the VM twice, but once that's all squared away we can start creating some test materials to find out what it can actually do. (For instance, does it have some codecs built in, and if so, which are they? Can it use any codecs on your machine?)
