The registry basically holds a central storage list of all the DLL files on your PC (it's called the "DLL Path References" list) and is what every software program uses on your system to load all the DLL files on your system. This list often gets damaged, preventing programs like FireFox from being able to read the DLL files that it needs. You should use a 'registry cleaner' to fix this problem for good.
