Why do you want to copy prefs.js to other computers (profiles) ?

This file contains profile specific user_pref settings and it is usually not a good idea to copy this file. There are other ways to transfer settings or initialize settings like autoconfig.cfg or policies.json.

Because I want to copy about:config setting to another computer, like https://support.mozilla.org/en-US/questions/1322272. After I test, I should copy the file to do it.
