Firefox is undergoing a gradual overhaul of its entire architecture that will bring dramatic performance, stability, and security improvements. https://wiki.mozilla.org/Quantum
During this process, Mozilla's work on the Rust language and technologies being developed presently under the Servo engine are being systematically integrated to replace existing Firefox components. One of the trade-offs in this process, is that the XUL customization framework that has been historically used to allow for near-unlimited customization is being retired, because it is a significant architectural roadblock to multithreaded and multiprocess Firefox and a significant source of performance impacts. The successor, WebExtensions is very similar to Chrome extensions, and more limited, but I recall there's ongoing work to make it more functional. I'm not sure of the degree of theming that will be possible though.
