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?

Solution 1

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

Solution 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:

Solution 3

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

Solution 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.

Solution 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

How about accepting vossad01 answer ?

...or the other one, doesn't really matter. Accept you should, though.

And it's on central column on the top of the screen (for those who haven't an english version of the settings, in fr : "Préférence générales/activer les journaux persistants")

I wonder how could they possibly do such a bad job cloning firebug. Which is all they really needed to do. Those guys must be blind or something.

Just in case anyone is wondering, this is how you do it in Chrome DevTools as well, the checkbox is along the top bar in the Network tab.

Hooray - that's the solution for Firefox 93
