Why do some add-ons not work (properly) with Pale Moon?
This can be caused by several different things, the most important: • Hardcoding: some add-ons hardcode calls to Firefox in its compiled state. Since Pale Moon is a different binary than Firefox, this kind of coding will never work for any build that is not exactly Mozilla Firefox’s distribution. • Naming: some add-ons or external programs expect the program to be called “firefox.exe” – a simple problem with a simple solution for the add-on programmers to implement. • Use of components not present in Pale Moon: If an add-on tries to use components that are specifically excluded from Pale Moon (like accessibility features, ActiveX, parental controls) it will fail. That being said, most add-ons function without a hitch.
