How to run script with root privileges by normal user
C code:

    #include <stdlib.h>
    #include <sys/types.h>
    #include <unistd.h>
    //#include <iostream>
    //using namespace std;
    int main(int argc, char** argv) {
     system("echo 0 > /sys/devices/platform/acer-wmi/leds/acer-wmi::mail/brightness");
      return (EXIT_SUCCESS);
     }

then gcc this code as root, then set the SUID bit and the SGID bit to 1 of the executable.

To fix widget problem in Firefox, Mozilla
It’s no Firefox bug but a KDE one. The fix that worked for me is to install the package “gtk2-engines-qtcurve”,
then open kcontrol and go to Appearance -> GTK Styles and change the GTK Styles to “QtCurve”.
