Firefox does not delete history on exit

For months now, Firefox is not deleting the history on exit, despite the option being ticked. Here is what I tried already:

  • Made sure the option to delete the history on exit is actually ticked
  • Made sure the sub-options describing what data to delete are all ticked
  • Unticked and re-enabled the aforementioned options
  • Diabled all addons and restarted the browser
  • Disabled sync and restarted the browser
  • Enabled Troubleshoot Mode and restarted the browser
  • Followed the support article regarding this issue: http://mzl.la/1BAQrbZ (except the nuclear option)

Manually triggering the deletion of history and cookies does still work. Following are the prefs.js options concerning privacy: user_pref("privacy.clearOnShutdown.offlineApps", true); user_pref("privacy.cpd.offlineApps", true); user_pref("privacy.cpd.siteSettings", true); user_pref("privacy.donottrackheader.enabled", true); user_pref("privacy.history.custom", true); user_pref("privacy.purge_trackers.date_in_cookie_database", "0"); user_pref("privacy.sanitize.pending", "[{\"id\":\"newtab-container\",\"itemsToClear\":[],\"options\":{}},{\"id\":0,\"itemsToClear\":[\"cache\",\"cookies\",\"offlineApps\",\"history\",\"formdata\",\"downloads\",\"sessions\",\"siteSettings\"],\"options\":{\"progress\":{\"clearHonoringExceptions\":true}}},{\"id\":1,\"itemsToClear\":[\"cache\",\"cookies\",\"offlineApps\",\"history\",\"formdata\",\"downloads\",\"sessions\",\"siteSettings\"],\"options\":{\"progress\":{\"clearHonoringExceptions\":true}}},{\"id\":\"shutdown\",\"itemsToClear\":[\"cache\",\"cookies\",\"offlineApps\",\"history\",\"formdata\",\"downloads\",\"sessions\"],\"options\":{}}]"); user_pref("privacy.sanitize.sanitizeOnShutdown", true); user_pref("privacy.sanitize.timeSpan", 0); user_pref("privacy.trackingprotection.enabled", true); user_pref("privacy.trackingprotection.socialtracking.enabled", true); user_pref("privacy.userContext.enabled", true); user_pref("privacy.userContext.extension", "CanvasBlocker@kkapsner.de"); user_pref("privacy.userContext.ui.enabled", true);

Is there anything else I could try, except nuking my profile?

select Settings. Select the Privacy & Security panel and go to the History section. In the drop-down menu next to Firefox will, choose Use custom settings for history. Select the check box for Clear history when Firefox closes.
