In particular, Firefox is compiled with the most conservative of settings, to ensure that it'll run on even ancient CPUs. And Pale Moon also drops support for Internet Explorer's ActiveX and ActiveX scripting technology, which also offers a security benefit as it means the browser can't be infected by malicious ActiveX controls. The crash report has also been stripped out, as it's designed to work with server-side technology that isn't available on. The program has been made more lightweight, for instance, by stripping out little-used components like the accessibility features, and the parental controls. Pale Moon is a customised version of Firefox, which has been carefully optimised for speed and efficiency.
