I have followed the forum suggestions and performed a clean uninstall and reinstall. The version currently running is 23.0. The error shows when opening Firefox but goes away and launches the browser. Is there a permanent fix for this and what is the cause?

Some files are now packed in a few larger files or code has been moved to remove smaller files, so there is nothing wrong about no longer seeing xpcom.dll and possibly a few other files.

  • Bug 852950 - Kill xpcom.dll/libxpcom.so/xpcom.dylib
  • Bug 648407 - Fold NSPR and NSS into mozjs (for Windows) or libxul (for other platforms)

If there are problem then do a clean reinstall and be sure to delete the Firefox program folder before installing Firefox.
