Answer : No, it is not possible to use another push service. In Firefox, you can do it by modifying the dom.push.serverURL preference, but obviously you'd need privileged access to alter the value of the pref.

Solution for target Sdk 21 If you want to support Lollipop Material Icons then make transparent icons for Lollipop and the above version. Please refer following: https://design.google.com/icons/ Please look at http://developer.android.com/design/style/iconography.html, and we'll see that the white style is how notifications are meant to be displayed in Android Lollipop. In Lollipop, Google also suggests that we use a color that will be displayed behind the white notification icon.
