Download defineBrowser.js Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying defineBrowser.js to your appropriate Windows system directory. Comodo Group typically does not release Comodo Dragon JS files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing defineBrowser.js and all other JS files for Comodo Dragon. An incorrectly installed JS file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
