I just compiled Firefox for the first time and now that i have i want to take my knowledge of add-ons to the next level, how would i go about compiling a custom page-mod content script?
Edit, doesn’t matter, I’m moving to another browser.
Are you talking about Add-on SDK content scripts? They are written in JavaScript, there is nothing to compile, see https://developer.mozilla.org/en-US/Add-ons/SDK
