You probably have script debugging enabled, to disable:
Start Internet Explorer
Click Tools
Click Internet options
Select the Advanced tab
put check mark next to "disable script debugging (Internet Explorer)
put check mark next to "disable script debugging (Other)
click OK
restart Internet Explorer
Programs are generally set to open you default browser as defined by Windows. easiest way to set Firefox as default browser is to:
Open Firefox
click Tools
Options
Advanced
click Check Now
Note the script errors may continue in programs even if you use Firefox as the browser, disable script debugging in Internet Explorer anyway (this is generally the recommended default setting anyway)
