Can I prevent the Firefox developer tools network panel from clearing on page reload?

Question

I would like to observe the contents of a POST request whose successful completion results in a location.reload() - when I try to capture this request in the Network Panel of the Firefox developer tools, I find that the page reload clears the list of captured events. Can I prevent this clearing?

Answer 1

From Firefox 31 onwards you can use the "Enable persistent logs" setting to prevent the Network Monitor from clearing the list on reload.

Answer 2

Despite knowing the name for the setting is "Enable persistent logs", it took me a while to find it on the settings page. I hope this helps:

Answer 3

I couldn't find this setting in Firefox 57. The setting has been moved to the network tab itself, above the log table

Answer 4

Roughly three years after BeetleJuice's update, it seems to have moved again - now, you need to click the gear icon on the far right side for the option to appear. Hooray for our ever-changing user interface soup.

Answer 5

If "Enable persistent Log" settings is not available in the devtool settings, you can go to about:config(type this in the URL box and enter) page and search for persistlog and change it from there(toggle button on the right).

I can see two options and enabled both. :)

devtools.netmonitor.persistlog, devtools.webconsole.persistlog
