nsSetDefaultBrowser.js file errors often occur during the startup phase of KompoZer, but can also occur while the program is running.

Most JS errors are due to missing or corrupt files. Your nsSetDefaultBrowser.js file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with KompoZer), or deleted by a malware infection.

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


CAUTION : We strongly advise against downloading and copying nsSetDefaultBrowser.js to your appropriate Windows system directory. Open Source typically does not release KompoZer 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 nsSetDefaultBrowser.js and all other JS files for KompoZer. An incorrectly installed JS file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
