I wonder how you retrieve the data from Firebug, but normally this is done using the HTTP Archive (HAR) format <http://www.softwareishard.com/blog/har-12-spec/>.
Note that Firebug is merged into the Firefox DevTools since Firefox 49.0 <https://blog.getfirebug.com/2016/06/07/unifying-firebug-firefox-devtools/> and Firebug 2 stops working once multi-process Firefox is enabled. Unfortunately the Firefox DevTools don't output the 'load' and 'DOMContentLoaded' events to HAR yet (see https://bugzil.la/1174091), which you need for your measurements, but this issue is actively worked on already. You may also be interested in the HAR Export Trigger <https://addons.mozilla.org/firefox/addon/har-export-trigger/> extension, which allows automatic export of the network request data (similar to NetExport for Firebug).
