No, thats the point in private, there is no history. But you can all have your own profiles and using profilemanager to switch between them "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -profilemanager

You can also start profilemanager by writing in search (or run) option on your startmenu firefox.exe -ProfileManager

read about it here: https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles

I found this link on a add-on that can put password on your profile. https://nic-nac-project.org/~kaosmos/profilepassword-en.html#PPFF Good luck

You can bookmark pages that you are interested in and want to keep.

You can save a copy of the current session data.

You can open the Browser Console (Firefox/Tools > Web Developer). Paste the JavaScript code in the command line and press the Enter key to run the code.

• Toggle the devtools.chrome.enabled pref on the about:config page to true to enable the command line

var ss = Cc['@mozilla.org/browser/sessionstore;1'].getService(Ci.nsISessionStore);
var ssjsonstr = ss.getBrowserState();
var output = ssjsonstr;

var fp = Cc["@mozilla.org/filepicker;1"].createInstance(Ci.nsIFilePicker);
var stream = Cc["@mozilla.org/network/file-input-stream;1"].createInstance(Ci.nsIFileInputStream);

fp.init(window,"",Ci.nsIFilePicker.modeSave);
fp.defaultString="session.json";

if (fp.show() != fp.returnCancel){
var stream=Cc["@mozilla.org/network/file-output-stream;1"].createInstance(Ci.nsIFileOutputStream);
stream.init(fp.file,0x04|0x08,0644,0);
stream.write(output,output.length);
stream.close();
}

You can look at this post in this MozillaZine forum thread about inspecting a sessionstore file.
