I am using Windows 7 and I've been playing with the Firefox browser for a while. I want to create a kiosk app using it, I installed a plugin for that, but the problem is that when I start the Firefox app, if I press Shift, it enters safe mode.
I read some guides on Google that tell me to edit chrome/browser.jar but I have no such file in my Firefox folder.
I need some help for disabling the feature that lets me enter safe mode by pressing Shift.
You cannot really disable safe mode by editing text files, the handling of the Shift key is inside compiled code. You can however disable the dialog that pops up by removing this code from components/nsBrowserGlue.js:
// check if we're in safe mode
if (Services.appinfo.inSafeMode) {
Services.ww.openWindow(null, "chrome://browser/content/safeMode.xul",
"_blank", "chrome,centerscreen,modal,resizable=no", null);
}
You can also leave extensions enabled in safe mode. For that you will have to also edit modules/XPIProvider.jsm and remove all occurrences of code like:
if (Services.appinfo.inSafeMode)
return false;
Both files can be found inside the onmi.ja archive in the Firefox directory.
That said, the proper solution to this problem would be running your own application on top of XULRunner which would allow you to design your own user interface for kiosk mode. Sadly, Open Kiosk (which is probably what you are using) is ancient and predates XULRunner.
I managed to disable Firefox session restore and safe mode tweaking these two preferences:
browser.sessionstore.resume_from_crash => false
toolkit.startup.max_resumed_crashes => -1
