I have created a new Firefox profile. Now I want to copy my settings of the Developer Tools to this new profile. This should also include the custom device settings for the Responsive Design Mode. Is there a file (or files) in the profile-folder that contains these settings, and can I copy this file (or files) to the new profile? I found this link about copying profile files, but it doesn't mention devtools settings.

Such settings are stored in prefs.js. Best is not to copy this file to a new profile since it stores internally used meta data that is profile specific, but only copy user_pref() lines you need to prefs.js in the new profile with Firefox closed.
