Its better to just go through the settings yourself then rely on arkenfox. This just adds a middleman into the process of keeping your settings updated.
In addition, if you use user.js then you essentially cannot change those settings at runtime (via about:config or otherwise), because your user.js will override the settings on next startup. Maybe that’s desired for some, but good to keep in mind nonetheless.
I don’t think that could work. Not unless we are talking about different things, or unless you run their updater script everytime before starting Firefox.
If you use user-overrides.js, it adds your custom preferences at the bottom of the user.js, as the prefs are read from top to bottom, if a new duplicate exist in your user-overrides.js but with a different value the new value would be used as it is at the bottom.
Yes, but that is not what I’m talking about. What I mean is that when Firefox is running and you go to change some setting in say, Settings page, then the new value for that preference is stored into prefs.js (at latest on Firefox shutdown, it might remain only in-memory for some time I’m not sure). Anyway, the new value persists only for that browser session, because on next startup whatever value was set by user.js will override it.
Sure. For simplified example have only the following in your user.js file:
user_pref("browser.tabs.warnOnClose",true);
Start Firefox
Observe that the pref is indeed true
Go to Setting > General, observe that Confirm before closing multiple tabs is checked
Uncheck the option
In about:config observe that browser.tabs.warnOnClose is now false
Restart Firefox
Observe that the pref is again set to true
The reason is also very simple. Firefox will never write anything to user.js - thus any changes you do at runtime will only be stored to prefs.js. However, user.js always overrides prefs.jsat startup.
Have you seen the user.js, you have to change a lot of settings and you cannot keep up to date with them, secondly Arkenfox prefers you to go over their user.js by your self and their updater script has the -c flag to show you the difference between current user.js and new user.js
Overall it would be very difficult to manage something like this on our own as most things are not visible on the settings page of Firefox

There’s the provided user-overrides.js that’s meant to do this

Have you independently confirmed this?
What is preventing
user.jsfrom doing exactly what you’re describing right now on your system?Sure. For simplified example have only the following in your
user.jsfile:user_pref("browser.tabs.warnOnClose",true);Confirm before closing multiple tabsis checkedbrowser.tabs.warnOnCloseis now falsetrueThe reason is also very simple. Firefox will never write anything to
user.js- thus any changes you do at runtime will only be stored toprefs.js. However,user.jsalways overridesprefs.jsat startup.Understood, thanks. So on a clean install, I’m assuming
user.jsis either empty or missing, correct?Have you seen the user.js, you have to change a lot of settings and you cannot keep up to date with them, secondly Arkenfox prefers you to go over their user.js by your self and their updater script has the -c flag to show you the difference between current user.js and new user.js
