A JavaScript script only works on Internet Explorer when the Internet Explorer Developer Toolbar is visible

Question

I got a script working on Firefox 5 but not with Internet Explorer 9. When I just open the Internet Explorer Developer Toolbar addon and try the same actions as befor

Answer 1

Is your script accessing or running any methods that are only available when the developer toolbar is open, such as console.log? For example, running console.log when console is undefined because the developer toolbar isn't open will cause an exception to be thrown.
