{{ gecko_minversion_header("2.0") }}{{ draft() }}

Firefox 4 achieves performance improvements by moving many of its internal parts from being standalone files or sets of JAR files into just one JAR file called omni.jar; this reduces the amount of I/O needed to load Firefox.

Note: When extracting omni.jar, you may incorrectly get false warnings from some virus protection software.
