Cookies clearing after Firefox restarts even with user-overrides.js file

[candroid-man]

Yesterday I updated my Arkenfox configuration to the latest version, and ever since then cookies have been clearing every time I restart Firefox. However, I used the same user-overrides.js file before and after the update.

user_pref("keyword.enabled", true);
user_pref("privacy.resistFingerprinting", false);
user_pref("privacy.resistFingerprinting.letterboxing", false);
user_pref("signon.rememberSignons", false);
user_pref("privacy.clearOnShutdown.cookies", false);
user_pref("network.cookie.lifetimePolicy", 0);
user_pref("browser.newtabpage.enabled", true);
user_pref("browser.startup.page", 1);
user_pref("browser.startup.homepage", about:home);
user_pref("services.sync.prefs.sync-seen.services.sync.prefs.sync.privacy.clearOnShutdown.cookies", false);

None of the checkboxes within settings regarding the deletion of cookies are checked, so I'm really confused as to what is causing this. Is there a new pref that was added in a Firefox update?

Read the changelog #1526.

Short: Use exceptions or set privacy.clearOnShutdown.cookies=false. edit: it's set, didn'T saw it.

user_pref("browser.startup.homepage", about:home);

syntax error

What are the values of the relevant prefs on about:config?

[rusty-snake]

How did you checked the cookie clearing? Just by noticing that you are logged out somewhere or by looking at it on about:perferences?

[candroid-man]

Both

[candroid-man]

Also, may I ask what syntax error is there is user_pref("browser.startup.homepage", about:home);? Because it doesn't work, but I couldn't figure it out

[rusty-snake]

The value must be a boolean, an integer vor a string. about:home is none oft them. You likely want "about:home".

Update: It seems this issue is only affecting certain websites. ProtonMail and Piped don't get cookies saved, but sites like Reddit and GitHub do. These are just the sites I have tested, I really have no idea what could be causing this

Read my first comment again.

You said that you checked on about:preferences that cookies got deleted. Did you really done this? And all cookies got deleted? Apparently not.

[rusty-snake]

GitHub handles "cross session login" with "normal" cookies.
ProtonMail handles "cross session login" with localStorage and uses session cookies for in session authentication.

And read the section in the user.js. Just search for cookie in the user.js and find it.

user.js/user.js

Adding user_pref("privacy.clearOnShutdown.offlineApps", true); to my user-overrides.js file resolved the issue, thank you for the help!

[Thorin-Oakenpants]

It's ALREADY true. So many conflicting comments about what is or was done, set, changed, confirmed

user.js/user.js

Line 787 in 0dba336

user_pref("privacy.clearOnShutdown.offlineApps", true); // Site Data
