Is there any way to open this directly with Chrome? – Pacerier Dec 29 '14 at 8:32

This has always baffled me - why does Chrome allow you to save HAR files but not open them? – Monkpit yesterday

.har seems to be an HTTP Archive Spec file. You can use HTTP Watch to open such files. FWIW those are JSON files
