This is rare, though - more extensions install and run just fine. If they've assumed that the browser's program name is firefox.exe, say, or they're using components that Pale Moon has stripped out, like the Parental Controls, then you'll probably find they don't work.

The browser does have one potential down side, in that it may be incompatible with some extensions.

So how much faster can the browser be? That's a tricky question, as performance varies greatly depending on what's being tested. Pale Moon, though, is optimised to take full advantage of modern processors, and this can give it a huge advantage over Firefox in some areas. 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.
