I opened FireBUG and expected it to detect JS errors, but it was useless... The compatibility of Javascript (JS) script code in various browsers is a very troublesome problem. After some debugging and searching, I finally solved the setTimeout JS The code is invalid and incompatible under Firefox and cannot be run and executed. Currently, this setTimeout is well compatible with IE6, 7, 8, 9, as well as Google Chrome, Firefox, Safari, and Opera.
