In this beta release, for both Desktop & Mobile, we fixed some issues in Javascript, some stability fixes, etc.
We also increased the memory size of some components to decrease the number of crashes (example: bugs <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=869208">869208</a> & <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=1124892">1124892</a>)
