Seems that Firefox 29 will have the Firefox Accounts that allow the online synchronization of the settings, themes and other stuffs for the browser. It should be similar to the one in Google Chrome browser that the synchronization takes place in various devices. However, I don't know if all the add-ons/plugins/extensions will be synchronized across multiple devices. Previously, even the Opera web browser is using the Google Chrome GUI along with some changes.
If the GUI is approved, they will decide to put it in Firefox 29 in mid-April this year. There will be two groups so far. One is the Australis project builds section and the other is the Mozilla-Central section which doesn't have the Australis code at all.
