Thanks. Our Firefox support isn't great at the moment. Also, we don't intend Ionic apps to be run in mobile browsers, but rather native UIWebView type shells. We are looking into support Firefox OS, though.
For instance, it doesn't seem to be possible to interact with the side-menus example at all; and in the nav bars and tabs example, after tapping on the cat link, I could find no way to go back again (apart from through the browser back button, which wouldn't be present in an app view).
(This is with FirefoxOS 1.2, which runs things like the Twitter mobile HTML app quite well. Worth testing if you can get access to a FirefoxOS device, it'd be great to see this working well on it.)
I must say I find it a bit problematic, philosophically, that an HTML5 app toolkit should be designed for a single platform and should have to be "ported" to new ones. What about it is so platform-specific?
Also layout issues along with not being able to click on the examples link on this page. Wasn't able to actually use the examples. Android 4.4 (N4), aosp browser.
