Overrides won't work

[cruthachail]

I've been trying to set my overrides to restore my previous session and to not clear my history or downloads whenever closing, but the overrides don't appear to be persisting. Whenever I close then re-open my browser, the tabs I previously had all vanish. Below is the user-overrides.js that I'm currently using.

/*** MY OVERRIDES ***/
/* startup & session restore: 0102 + 1020 */
user_pref("browser.startup.page", 3); // 0102 3=resume previous session: requires history to be kept
user_pref("browser.sessionstore.max_windows_undo", 30); // default 3 windows
user_pref("browser.sessionstore.privacy_level", 0);
user_pref("browser.sessionstore.resume_session_once", true);    // 1020
   //user_pref("browser.startup.homepage", "https://www.startpage.com/");   //0103
/* don't clear things on close: 2803 */
user_pref("privacy.clearOnShutdown.cache", false);
user_pref("privacy.clearOnShutdown.cookies", false);
user_pref("privacy.clearOnShutdown.history", false); // required for session restore
/* if I use Ctrl-Shift-Del: match clearOnShutdown: 2804 */
user_pref("privacy.cpd.cache", false);
user_pref("privacy.cpd.cookies", false);
user_pref("privacy.cpd.history", false); // fuuuck: don't accidentally wipe my session restore
/* fucking autoplay */
user_pref("media.autoplay.default", 2); // 2030 0=Allowed (default), 1=Blocked, 2=Prompt
/* END: custom check for achievement award ***/
user_pref("_user.js.parrot", "Fukyeah, I survived the overrides and got this T-Shirt");

Could anyone lend me a hand and perhaps point me in the right direction?

Did you run the updater?

Did you run the updater?

I did, it would appear the following below had been the culprit.

/* Additional settings that could be causing issues with restore session. */
user_pref("privacy.clearOnShutdown.cache", true);     // [DEFAULT: true]
user_pref("privacy.clearOnShutdown_v2.cache", true);  // [FF128+] [DEFAULT: true]
user_pref("privacy.clearOnShutdown.downloads", false); // [DEFAULT: true]
user_pref("privacy.clearOnShutdown.formdata", true);  // [DEFAULT: true]
user_pref("privacy.clearOnShutdown.history", false);   // [DEFAULT: true]
user_pref("privacy.clearOnShutdown_v2.historyFormDataAndDownloads", false); // [FF128+] [DEFAULT: true]
