How do I make firefox restore previous session every time it crashes?

I really like the "restore previous session" window that shows up sometimes when firefox crashes, being able to pick and choose which tabs and windows to reopen. My question is are there any add-ons or ways of making it so this happens every time I have to reopen firefox? Right now it only does it occasionally, other times it automatically reopens every tab loading them as I go which makes the process of finding which windows I want and getting back up to speed much lengthier. This is quite an annoyance because you'd think after force quiting firefox would default to this every time, but usually it reopens every tab and I have to try and purposely crash the browser hoping I'll get the "restore previous session" window. Any help with this would be greatly appreciated. Thanks.

Yes, you can. Firefox will try to automatically restore once. If that fails, then it gives you the screen to choose. To prevent automatic restoration and always go straight to that windows/tabs list, change a setting here:
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the search box in that tab, type or paste '''sessions''' and pause while the list is filtered
(3) Double-click '''browser.sessionstore.max_resumed_crashes''' and change the 1 to a 0 (a zero) and OK that.
(4) You can close this tab now.
Hopefully you won't need to test it any time soon -- if you are crashing a lot, we should try to figure out how to stop that.

  • How do I get the restore previous session

    1st how do I get the history menu to have functioning "Restore previous session" and "Recently Closed Tabs" and "Recently Closed Windows" options? They are not usually in black but gray, not useable.
    2nd, how do I get to articles which explain things like the history menu and how to use it without asking a question through this process?

    Make sure that you do not run Firefox in permanent Private Browsing mode.

  • Firefox opens the old browsing window (previous session) every time i try and open a new window, how do I change this back?

    Every time I go to open a new window, the old one will come up instead. For a while it was working fine, then I kept needing the old window and would use the 'restore previous session' feature to access this. However, even after I didn't need it anymore (and without me selecting the feature, it would still open the previous session.

  • How do I restore previous session one time only.

    I closed Firefox by mistake.
    I reopened it, hoping to Restore Previous Session.
    Unlike other browsers, I found no easy link nor mention in any of the dropdowns from the menu on top left.
    I went to the Archives, but none of the solutions worked:
    1) I do not want it to auto restore the previous session, I only want it to do it this one time.
    2) None of the things mentioned to click on in the help articles exist in this version of Firefox.

    Go to [http://kb.mozillazine.org/About:config About:config] find (type in the bar) [http://kb.mozillazine.org/Browser.sessionstore.resume_session_once browser.sessionstore.resume_session_once] and change it to TRUE (by double-click on it).

  • How do I turn off "restore previous session"?

    When I open FireFox-it gives me the option to "restore previous setting" How do I turn this feature off?

    Hi Tater23,
    Try going to ''Tools > Options > General'' and see if you have set Firefox to restore your previous session on startup. For detailed information on setting up the homepage, you should take a look at the Knowledge Base article [[How to set the home page]].
    Hopefully this helps!

  • I do not want firefox to ask me if I want to return to a previous session every time I open it

    I think every time I turn the computer on or re open Firefox I am asked if I want to return to a previous session . I do not want to be asked.

    That can happen if Firefox isn't closing properly.
    Try to use File > Exit Firefox to close Firefox if you are currently using the close X on the title bar.

  • How do I make my selected Persona appear every time Firefox opens?

    In an earlier Firefox version, my favorite selected Persona always appeared at the top every time I opened Firefox. I now have version 4.0.1. What can I do so a Persona is automatically shown? In other words, I'm getting tired of selected a Persona every time I open a new Firefox page, so is there a setting within Firefox 4.0.1 to automatically show the Persona used in my prior Firefox window?

  • How do you get firefox 4 to save tabs and windows and restore them? Don't say set preferences to open them on startup or use restore previous session under history; those do not work. Or is it no longer possible to save windows and tabs?

    Question
    How do you get firefox 4 to save tabs and windows and restore them? Don't say set preferences to open them on startup or use restore previous session under history; those do not work. Or is it no longer possible to save windows and tabs?

    '''IT'S A EASY AS IT SHOULD BE.'''
    This is essentially paulbruster's answer, but I've added the steps some might assume, but which aren't so obvious to those of us who are new at this, like me.
    This solution might ''appear'' to be long and complicated, but after you follow the directions once, you'll find it's quick, clean, and simple. Almost like they designed it this way.
    # If you haven't already, open a bunch of tabs on a few different subjects.
    # Click the List All Tabs button on the right side of the tab strip.
    # Select Tab Groups.
    # Create a few groups as described [http://support.mozilla.com/en-US/kb/what-are-tab-groups#w_how-do-i-create-a-tab-group here] , i.e. just drag them out of the main thumbnail group into the new groups they create.
    # Now click on any thumbnail in any new group, but not the original big default group you may have left some tabs in.
    #A regular Firefox window will open, but'' only the tabs in that group will be visible.'' You also now have the Tab Groups button in the tab strip.
    # Right click on any tab, and there it is: Bookmark All Tabs. Click on it in the list of options. Or you can hit Ctrl+Shift+D instead and go straight to the dialogue box from the tab without any clicks. But don't go looking for this familiar option anywhere else, 'cause it's not there.
    # Now pick an existing folder or create a new one just like you would have before and '''shlpam!''' there they are. New folders are supposed to end up in the Unsorted category all the way at the very bottom, but for some reason mine show up at the bottom of my last sorted category.
    # DO NOT CLICK THE UPPER-RIGHTMOST X to close this group of tabs. This will close ALL of your tabs in all groups, currently visible or not. At least it asks if you're sure first. Instead, click your new Tab Groups button to return to the Boxes 'O Thumbnails window, and click the X in the group box you just bookmarked.
    # Click on another thumbnail to repeat the process with another group, or click on a thumbnail in the big default box to return to the original FF window. You can also click the Tab Groups button at the upper right, or Ctrl+Shift+E, which will also get you ''into'' the Boxes 'O Nails window ''from'' FF.
    # So now when you reopen FF after shutdown, simply select your folder from your Bookmarks and Open All in Tabs. '''Just like paulbruster said. '''

  • The restore previous session button is not working on Firefox on any of my three machines. How can I fix this?

    I have a desktop at work, and a desktop and laptop at home and just recently the "restore previous session" button that comes up when I use the desktop icon to start a Firefox Web browser session does not work. It is there and I click it but nothing happens. I have Windows 7 on the two computers at home and thought that is what I had on this computer at work, but it may be Vista. It's not XP.

    Had this trouble myself, just did some research and solved it!
    Go to the '''Help''' menu, go to "'''Troubleshooting Information'''"
    On the new window, click "'''Open Containing folder'''" next to ''Profile Directory'' (This opens the folder on your PC where Mozilla stores some settings, like a tab history)
    In the new Windows Explorer window, Find the file "'''chromeappsstore.sqlite'''"
    You'll want to close Firefox and then '''delete''' that file (don't worry, Firefox will create a new one, and you won't even lose the open tabs)
    Start Firefox again and the button should work!
    (For completeness's sake, the profile folder for windows7 is: C:\Users\Tiberion\AppData\Roaming\Mozilla\Firefox\Profiles\c6xu23fh.default\
    where you replace Tiberion with your own username, and the random characters in the final folder will be different.)

  • Windows XP crashed and Firefox 5.0 closed improperly. When I relaunched it, I mistakenly clicked New Session button instead of Restore previous session. How can I get that session back now? Thanks

    I am on Windows XP/Firefox 5.0 Computer crashed overnight closing Firefox improperly. When I relaunched I got choice to restore previous session. By mistake I clicked on Start New Session. Now I cant restore that session through Menu, relevant buttons are greyed out. I cant see any pertinent information online either. I appreciate any help. Currently I am digging through the history but for some of these tabs I dont know when I opened them (may be a while ago).

    I don't have a good sense of what is going wrong.
    Was Firefox stable in step 3 -- open with no sessionstore.js file and then exit?
    If that was stable, it might be easiest to cull the open URLs from your sessionstore.js file and re-open the most important ones manually. You will lose the ''detail'' of your session on those pages (e.g., data you had entered into a form), but if that's okay, it might be the next step.
    I found a script on mozillaZine that will extract URLs from the sessionstore.js file; I just changed the formatting of the output. To run the script:
    (1) Return to your profile folder and rename sessionstore.js to sessionstore.old again, then copy it to a convenient location
    (2) Start Firefox (it should be in a new session)
    (3) Open the following link, select all (Ctrl+a), copy (Ctrl+c) to copy the script to the clipboard: http://dev.jeffersonscher.com/sessionstore_reader.txt
    (4) Open the <s>Error Console</s> <u>Browser Console</u> (Ctrl+Shift+j), click next to <s>Code</s> <u>the caret (>>)</u> and paste, then press Enter <s>or click Evaluate</s>
    (5) A file selection window should appear. Navigate to the convenient location and open sessionstore.old from there.
    (6) As long as the file is not corrupted, a new tab should open with a list of all the URLs the script found in the file. You can save this page for future reference if desired. Also, you can close the <s>Error</s> <u>Browser</u> Console now.

  • The Firefox about:home page always shows "Restore Previous Session" and opens random things even after a clean exit.

    I don't like anything opening automatically when I start Firefox, so before Firefox 4 I set Firefox to open a blank page when it starts. I still had set a page I visit frequently as my home page, so I could get to that page quickly by pressing the home button. If I needed to close Firefox it was nice and easy to have the option to save my session and close (I've already searched and read another post and answer on how to restore this feature in about:config). I understand that Firefox 4 always saves your session and you can restore it from the history menu, but then I would have to remember if I had anything open and click menu/History/Restore Previous Session.
    Now in Firefox 4 I have left the home page set to about:home so if I had tabs open when I closed it I would see the Restore Previous Session "button" the next time I start it. However, when I close all windows and tabs before exiting Firefox, the Restore Previous Session "button" will be sometimes be there. If I click it, it will open a random tab or window that I visited the previous day, which was NOT the last tab/window that I had open.
    If I do have tabs open when I close it, it does correctly re-open them when using the Restore Previous Session button, it only does this if I do a clean exit (close all tabs/windows before close).
    I tried deleting the sessionstore.js and sessionstore.bak files from my Firefox appdata directory (there were no other sessionstore.* files). This is a clean install of Firefox 4, I didn't install on top of Firefox 3.6.xx. I uninstalled Firefox 3.6.xx before installing and made sure to delete any leftover files in my appdata, programdata and program files directories.

    I thought about that before and tried it, and it doesn't seem to make a difference. I did it just now, I opened a blank tab and closed everything else, waited a minute then closed Firefox. I waited another minute and launched Firefox. The Restore Previous Session box was there on about:home. I clicked it and it opened a new window with about:home in it.

  • I want to Firefox resume previous session when it crashes, but I can't make it to do it when I set it to forget my personal data when closing.

    Until the most recent versions of Firefox (let's say FF 10 or 11), when the software crashed I had the option to resume the last session when reopening it. I could do this even when I made it clear all my personal data when closing it in normal ways (i.e., when I quit the program without crashing, Firefox would not keep any personal information).
    Now, however, Firefox will only restore the previous session after crashing if I don't make it clear personal data after normal quitting.
    How can I fix this? I want it to restore previous session only after crashing, not after a normal exit.

    Use these steps to remove saved (form) data from a drop down list:
    #Click the (empty) input field on the web page to open the drop down list
