hi irul2008, please perform a clean reinstall of firefox:

  • download the full firefox setup file from https://www.mozilla.org/en-US/firefox/all/
  • uninstall firefox on the machine
  • manually delete all remaining files in the firefox program folder, which usually resides in C:\Program Files (x86)\Mozilla Firefox\
  • reinstall firefox with the setup file obtained in step 1

afterwards please run a full scan of your system with different security tools like the free version of malwarebytes and adwcleaner! Troubleshoot Firefox issues caused by malware

Sounds that you have a .js (JScript) file in the "defaults\pref" folder that specifies to process a mozilla.cfg file.

If there are .js files present in the "defaults\pref" folder apart from the channel-prefs.js file that sets app.update.channel then open this file in a plain text editor like Notepad (Mac: TextEdit) and please post its content.
