Explanation
Firefox achieves performance improvements by moving many of their internal parts from being standalone files or sets of JAR files into just one JAR file called omni.ja.
This reduces the amount of I/O needed to load the application.
Chrome content, modules, non-binary components, and many other elements are packaged in an omni.ja file for each base directory.
