HI all! Hope you all are doing well.

I am using user.js file to harden my Firefox to the best possible way. I have few question about that process.

1. Where i can find the complete list of all active user_pref settings? All of the options i have to edit them. like user_pref("security.sandbox.content.level", 6); - now i have 6 by default but what is the range?

2. Is there any tool i can use to update my list with the latest entries, and to remove the obsolete entries?

3. Sandbox - what are the best possible ranges and settings for the below entries?

ser_pref("security.sandbox.socket.win32k-disable", true); user_pref("security.sandbox.content.level", 6); user_pref("security.sandbox.content.shadow-stack.enabled", true); user_pref("security.sandbox.gmp.win32k-disable", true); user_pref("security.sandbox.gpu.shadow-stack.enabled", true); user_pref("security.sandbox.gpu.level", 2);

Thanks well in advance! Firefox 116.0.3

Changing the default search engine programmatically is intentionally difficult to avoid abuse. Enterprise policies only allows this for ESR versions.

Can you please clarify - what abuse means?! I dont want to use google and that is shoveled into my face. I would like to switch to DuckDuckGo lets say? How is that abuse?

You can change the default search engine in Settings > Search.

Ye sure thanks, i am kind of aware, really not helpful... "i am not able to make browser.search.defaultenginename - to switch to DuckDuckGo...

I need a solution that works only with user.js. Thanks

Like written above, you can't set/change the default search engine via a pref as this was abused by malware in the past. Changing the default search engine can only be done via advanced JavaScript or via a policy if you use a Firefox ESR version. See SearchEngines:
