Let's have a look at some recently landed Web APIs for Firefox
So, without further ado (as there's been too much "to do" about it) let's take a look at what we presently have (landed or about to land) regarding our latest (Firefox) Web APIs.
You'll need the latest xul fennec builds to run these. Technically, these also run on the latest birch nightly, but that one is presently undergoing a major facelift due to rendering and related issues.
I'd suggest using a tablet. (For the SMS app, you'll need a phone with simcard and a special build, but we'll get to that presently).
All example testpages to which we'll be referring are available under the directory at: http://people.mozilla.org
