hi I noticed that the z1 and zr xperia are listed but not xperia z zr is basically same phone just dif camera and size to z. I running Firefox 26beta on a xperia z and apart from random crashes (not that often) and flash doesn't play properly. can Firefox 're-enable flash support. and my main question how do you set how many days etc Firefox keeps history and can someone at Firefox email me an email address so that when Sony make the 4.3 and 4.4kitkat update available will send info on any probs etc.
