How to restore a previous session to a record of old data of Firefox?

There was a power outage today while I was start of Firefox and the computer shut down instantly. Later, when I tried to open Firefox again, he started glitching, with the option to restore Session only resulting in empty tabs. I refreshed Firefox and now I have an "Old Firefox Data" folder.

I have a folder of sessionrestore-backups in this folder, a file 'previous.js '. How to use this file (or other folder) to access my lost session? It is possible at all?

Thanks for any help.

You can find these files in the sessionstore-backup folder:

previous.js (cleanBackup: copy of sessionstore.js from previous session that was loaded successfully)
recovery.js (latest version of the sessionstore written during runtime)
recovery.bak (previous version of the sessionstore written during runtime)
upgrade.js-<build_id> (backup created during an upgrade of Firefox)

You can copy a file in the sessionstore-backup folder to the main profile and rename sessionstore.js file to replace the current file (make a backup of the current sessionstore.js).

  • How to restore a previous session after firefox closed and deforested browsing history, is still any chance to get it there?

    Accidentally closed down the pc and firefox did not return with option restore previous session in the first screen even in history-Restory previous session is gray. My settings are own history after closing firefox.
    Y at - it no change to return on my tabs from previous session even browsing history has been cleaned? I'd appreciate your help!

    In general, FireFox will behave in 1 of 3 ways when restarting after a stoppage.

    1 kill Shutdown
    This occurs when the FireFox process ends with a TerminateProcess() appeal or if the process of FireFox crashes. It's a dirty, no cleaning is done. When restarting after this FireFox will show a dialog "well, this is embarrassing' with options to restore the items selected from the previous session.

    2 force Shutdown
    This occurs when another process ask FireFox to shut down cleanly (for example, a reboot of the PC) by a call to ExitProcessEx() and does not ask confirmation of the user. Normally, when this type of shutdown happens, Firefox will just restore all tabs and sessions without asking. However if Firefox is set automatically delete the history on shutdown, it may not. I suspect that this is your case. I would suggest to the FF team remove that history should be ignored in this case, only a stop of the user must delete the history.

    3 judgment of the user.
    That's when said user Firefox close (by selecting exit or by closing all the tabs etc...). Confirmation is requested to close all tabs (if enabled and more than 1 tab is open). When the computer reboots, nothing is restored.

    Unfortunately, if you have enabled clear auto history, there is no way to recover the previous session. I'm sorry.

  • How to restore a previous session after a crash when it is not available?

    We had a power outage, and when my computer is back she just opened a blank session. Restore previous session was not offered as an option - it is greyed out. I tried (probably foolishly) closing and reopening.
    Now, I read a lot of ways to restore them, but many of them that I don't really understand.
    I found the profile folder and a copy of the sessionstore.
    Instructions say to right click and hit properties and then select "previous versions". That's where I come off. I don't seem to have this as an option. There are "General" tabs, "script" of 'security' and 'details' all with several sub-options. I can't seem to find anything that says than previous versions. I even followed a statement that says to do on the record and not on the file, but there is no option called 'previous versions' on either.
    I'm (unfortunately) using windows 8.

    To use an old sessionstore instead of the current file, first of all, close Firefox. Rename sessionstore.js sessionstore.old file, and then rename the sessionstore.bak -datetime sessionstore.js file. When you start Firefox, if it is set to restore the tabs and windows of the previous session should only pick up. If it is set to start with your home page, use history > restore previous Session.

  • How to restore the previous session from a sessionstore.bak file

    When I tried to open firefox that it automatically updated and deleted the sessionstore.js file. I saved the sessionstore.bak in another case, closed mozilla, changed the extension bak in js in the folder "profiles" Firefox and opened it again, but nothing happened. If the sessionstore.bak file is large 13Ko and seems to contain all the links in my previous session.

    How I force Firefox to start a session by using the information in the sessionstore.bak or .js file, as it should?

    Hello lordsilver2, the method you tried is correct, if does not work maybe the sessionstore.bak (renamed sessionstore.js) is corrupted.

    First make a copy of the file (the renamed sessionstore.js) on your desktop and then try to create a new profile and move the copy in the new profile to see if it works. If the file is corrupt is not sure the books above.

    Thank you

  • How can I stop firefox trying to restore my previous sessions

    Since I updated to firefox 20.0 I had a problem with firefox. Whenever I start firefox I get a message saying that it is so embarrassing to try but not to restore my previous session and it gives me the opportunity to be close the page and go to the home screen, or to restore my previous session. My preferences has the show my home page selected, every time I close Firefox, I close the page by pressing the red x, and then I put the firefox icon or the tab of firefox at the top of my screen and select Exit. I have reset firefox twice and that no longer works.

    A possible cause can be that you first close all Firefox Windows and then close the Firefox application.

    Some noted that closing of Firefox (Firefox > Quit) while the browser window is always open works for them.

  • Home page search is not working / not Possible to restore the previous Session

    After the last update (version 29), the home page of default Firefox search bar has been completely non-functional. If I hit enter or press search, nothing happens. Another (possibly related) problem is that the button 'Restore previous Session' is never present. I can also restore the previous session by clicking on the option of history (it is always grayed out).

    When you look to the top How to start safe mode, I discovered how to reset Firefox to its default value of the plant. I did it and Voila! Problem solved.

  • Whenever I open Firefox, it restores my previous session without being invited.

    I set parameters so that when I start Firefox to go on my home page, which is just the Mozilla Firefox start page. Despite this option is defined, it always restore my previous session every time I open Firefox.

    One of the possible reasons are a statement in a user.js file. Firefox checks a file user.js at startup, and it replaces your own preferences. This article describes how to check for this problem as possible: How to fix preferences that will not save.

    Another possible reason is if Firefox does not close properly and is still recovering from a perceived fall. To see if this is the issue, you can change what Firefox works after an accident so that instead of automatically display tabs from the previous session, it shows you a list of the tabs. Here's how:

    (A) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

    (B) in the search above the list box, type or paste sess and make a pause so that the list is filtered

    (C) double-click the preference browser.sessionstore.max_resumed_crashes and enter 0 (that's a zero) and click OK.

    The next time Firefox starts if you get the screen saying 'it's embarrassing"and display a list of your last session tabs, then the problem is that Firefox crashes on shutdown.

    Does this help with your startup?

  • What can I do to find file extensions, please? I'm trying to restore my previous session on Firefox, & need help file extensions...

    I was told if I found the session files I would be better able to restore my previous browsing sessions... I am using Windows XP PRO SP3 32-bit.
    But I was also told that if I went to a particular place on Microsoft Windows, I know how to get the file extensions, so far I have had no luck with assistance here... hoping someone can help.
    Or... do you something if I activate a restore point which would be an easier option?
    I'm old & not a geek, if need you detailed instructions please

    Thanks in anticipation... I am very grateful to be able to request...
    Kind regards

    Session files are located in your profile folder and are named sessionstore.js and sessionstore.bak. If you have had an accident, FF load automatically and ask you if you want to use the session crashed.

    If you don't have an accident, you can load the last session in FF from the default home page by clicking on the restore session. If you have changed the default home page you can call it by adding on: houses a copy of your FF shortcut. Simply change as follows...
    Then, you will see this...
    Click on restore the previous session.

  • Firefox crashed and does not give me the option to restore my previous session.

    Hello

    I've been using firefox for a while now and so far, ive never had a problem like this.

    Firefox crashed last night while I was asleep, and when I woke up this morning to turn it back on, the crash reporter asked me that if I wanted to restart firefox, I did, but when it is loaded, instead of asking if I wanted to restore my previous session, he loaded a blank page which had a white patch is looking for unusual at the top where the tab bar is supposed to be , with the legs of loading below.

    The tabs that I had loaded were all very important to me and I would like to find a way to get back them if possible, however, I was unable to find anything on the other help pages that describes the solves my problem.

    Please help if you can, it would be greatly appreciated.

    PS I apologize for not to include an image of the window of buggy, it didn't occur to me to take a screenshot before I closed it.

    sessionstore.bak files are no longer used in current versions of Firefox, so they are probably for some time ago (seven 2014:20140923175406) and may no longer be of use.

    One possible way to inspect a sessionstore.js file or a file in the sessionstore-backups folder is open in a Firefox tab and to evaluate that JavaScript code in the Web Console (Firefox/tools > Web Developer).

    Paste the code into the Web Console command line and press the Enter key to evaluate the code.

    eval("ss = "+document.body.innerHTML.replace("<pre>","").replace("</pre>",""));
    sd='';
    for (var i = 0; i < ss.windows[0].tabs.length; i++) {
     var ent = ss.windows[0].tabs[i].entries;
     var last = ent[ent.length-1];
     sd+="["+(i+1)+"]:"+"<a href="+last.url+">"+last.url+"</a><br />";
    }
    document.body.innerHTML=sd;

  • Version 38.0.1 of Firefox will not restore a previous session by using Tab Mix Plus; all other versions prior to version 38.0 work.

    I installed all versions of Firefox to version 31.0 38.0 and the only one that does not restore a previous session using session Tab Mix Plus restore feature was version 38.0 or 38.0.1 (latest version).

    I think it's because of software (adware or virus) on your computer or Web sites you visit. Many of these change home pages without the consent of the user as a way to aggressive advertising or people of the scam. Generally, these target your browser by default, so even if you go to Maxthon, you might get some problem. To avoid this, you must use anti-virus software to find viruses and adware, then remove them.

    Even with the adware you can probably always restore your previous session by clicking on the "Firefox" > 'History' > ' restore previous Session ' (or 'History' > 'restoration of previous Session"If you do not have the"Firefox"button).
