In Chrome, I can customize the width of the columns in its developer tools’ network tab:

In Firefox, I can’t figure out how to do the same thing:

Is it possible?

Starting from Firefox 67 it is possible to resize the columns within the Network Monitor.


This feature is now available in beta version (v67.x). You will need to go to about:config and enable the flag devtools.netmonitor.features.resizeColumns.

For previous versions see Change columns size in Firefox Developer Tools
