I am developing a Firefox extension and want to open a custom html page where the user can adjust the settings. I am able to do it in different ways, but would like to use the standard Options button that is shown in the add-on manager of Firefox.
I have seen some documentation about it, but I am having problems on finding proper documentation for this function using the online Add-on Builder: Preferences system, Inline options, Simple prefs.
Does anybody know how to just add that standard Options button that is shown in the add-on manager and handle its click event to show a custom options page? (just like it's possible in Google Chrome)
