We ship Firefox and Thunderbird with Plasma integration patches. Those take a little bit to build. We provide them in the plasmazilla ppa. This has a releases ppa with the tested released versions. We also provide a builds ppa there where you can see the currently building or uploaded packages. Those are the ones we test before they land in the releases archive. You can see that 52.0.1 is already there. But we are also building and testing a 52.0.1esr version.
