Firefox 7 on Mac OS Lion Won't Restore Previous Session

Just recently I have tried using the Restore Previous Session button when starting Firefox, and it won't restore the previous session. I'm not sure why this is happening. I'm using Firefox 7.0.1 on Mac OS 10.7.2. I deleted Firefox as well as my profile and reinstalled using a new profile, and I'm still getting the same issue.

Yes, this is definitely a problem on Lion. What happens is a combination of both Lion and Firefox being dumb in opposite directions. Lion has this thing if you hit the "close" button on the window it doesn't close the program __unlike every other os, even other macs!!__ but it _looks_ like it closed. Since firefox doesn't count the window closing as a real close, it doesn't save anything. So if you hit the red "X", then right-click on the firefox icon and say "quit", and then open firefox, you lose everything. No session to restore from last time, nada.
Although you can try to always remember to right-click and say "quit", I really think firefox should fix this so the user experience is consistent across all OS's. That is, if you hit the red "X" on your window on your mac, it should save your session for when you open it again. Please firefox, pretty please.... :)
I have to switch between windows/linux/mac all day, so trying to remember different habits for each is a big PITB (don't get me started on "End" and "Home").
Every time I update flash on a mac (god I hate I flash, but necessary for some things), I "close" firefox, and I end up losing months of curated tabs that are "things I need to read eventually". It really, really sucks.

After updating adobe flash and restarting firefox for mac, as requested, can't restore previous session

using macbook pro with os 10.7.5, was recommended to update adobe flash while in firefox (22.0). did so, which required closing and restarting firefox during flash update. when complete, firefox opened automatically to adobe flash window and restore previous session was grayed out. can't figure out how to find and restore the tabs i had been using. related questions and answers don't find a solution. my settings are all normal and do not appear to have any relation to the problem. rather, it seems to be the closing and reopening of firefox associated with the updating of flash that nuked any memory of my previous session. is there a solution?

i found my own solution to my problem! first of all, DON'T QUIT FIREFOX -- to be sure the current undesirable session doesn't become the "previous session". instead, open a new window (command-N). in my case, it opened to my usual default url and, while in that window (either before or after closing the first browser window that had opened automatically after updating adobe flash), the "restore previous session" option in history menu reappeared! clicked on it and, from then on, things just worked normally.

My wordpress home page will not display any active information in Firefox 15 on Mac OSX Lion.

Hey All,
I've tried many things to resolve this issue, but none of them seem to be working. For some time now I have not been able to see the homepage of wordpress.com with full information i.e. stats, notifications, etc. I'm running Firefox 15 on Mac OSX Lion with the following settings and add-ons. I've tried disabling the various privacy add-ons one-by-one to no avail. Please help!

The only active thing I see on that page is the banner near the top which keeps changing: "For the cat pictures", "For the poet", etc. Do you not see that? I did not see any link for "Home". Try these pages:

Incidentally, it seems to me that you are using Mountain LIon, not Lion. Mac OS 10.8 is Mountain Lion.

Session Restore isn't working!!!!!!!! Both my mac laptop and Windows 7 desktop no longer respond when I click "restore previous session" Please get this fixed asap, as it is my most used feature on FireFox!

System Restore is not working!!! Both my mac laptop and now my Windows 7 desktop will not allow me to restore previous sessions.

Try to use the "Restore Previous Session" entry in the History menu instead.

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.)

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.

After quitting FF 8.01 on a Mac with OSX 10.5, restarting the Mac then starting FF, the offer to Restore Previous Session is grayed out. Is there any way I can recover the list of pages open when FF was last quit?

Had about 15 windows w/ tabs open. System was a little sluggish and had not been rebooted in weeks so I Quit FIREFOX. Restarted the Mac, then FIREFOX. Option to Restore Previous Session was grayed out. I haven't used that computer since, hoping not to overwrite record of previous session.
I've used the Restore Previous Session feature many times before without any problems.

You used the data. Verizon can not see what it was sued for. However your phone can see whats apps used the data. go to settings-data usage- there will be a place that says data usage cycle. line the dates up with your cycle. then there will be a bar graph below that extend bother white bars one all the way to the left and one all the way to the right. after those are extended below that will be a list of apps, there should be one that used over 2 gb and that will show you what app used that data in her purse

Firefox will not restore previous session in the same window?

Hello,
Every time I open Firefox and click the restore previous session button at the bottom nothing happens. That's the first part of the problem. Next, when I click on my history and click restore previous session, it does so but opens them all in a new window. It was only 3-4 days ago that this started happening. I would like to change what ever is causing this back to how it was as it is quite annoying when I have pinned tabs and I have to keep re-pinning them.
I am running the Developer version of Firefox.
Thank you.

Hello,
'''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
'''If Firefox is open,''' you can restart in Firefox Safe Mode from the Help menu:
* Click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
'''If Firefox is not running,''' you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac: Hold the '''option''' key while starting Firefox.
* On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
;[[Image:SafeMode-Fx35]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, theme, or hardware acceleration.

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.

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. '''

Is it possible to NOT have 'Restore Previous Session' option come up automatically every time you start Firefox?

A large envelope pops up mid-screen every time I start Firefox, asking if I want to restore previous session. I don't want all users after me to have this option, but don't want to keep an empty history either. Can I deselect this option somewhere? Looked around, but found nothing.

Unfortunately changing the options found under "Completely disable session restore" does not make any difference to this problem.

Does the restore previous session call get destroyed too with the new forget button in firefox

I have checked under startup to restore previous session ... Can it still if I use the new forget button since it states all tabs are closed ... so that would be last session to my thinking Rick Carter

I think there is a serious risk that your session history will be cleared, too. However, I haven't tested it yet. If you want to preserve a copy of your session history files while you experiment, you can back them up as follows:
Open your current Firefox settings (AKA Firefox profile) folder using either
* "3-bar" menu button > "?" button > Troubleshooting Information
* (menu bar) Help > Troubleshooting Information
* type or paste about:support in the address bar and press Enter
In the first table on the page, click the "Show Folder" button. This should launch a list of your settings files.
Look for a folder named '''sessionstore-backups''' and copy it in its entirely to a safe location such as your Documents folder.
You also should find a file named sessionstore.js which contains your current session windows and tabs. You could back that one up, too, but the recovery.js file in the sessionstore-backups folder should be identical or virtually identical (it may lag a little, but should be updated to be the same fairly quickly).

No restore previous session option available and can't find sessionstore.js in latest firefox version.

After a crash, I turned on my firefox to find the restore previous session option greyed out. So I go to my profile folder to find no sessionstore.js file, I assumed this is because the lastest firefox made changes to where the session store is stored now. Where is the session stored now and is there anyway I can restore my previous session? I really need it.

Firefox still uses the sessionstore.js file in the profile folder.
Only the sessionstore.bak file in no longer used and has been replaced by backups and previous versions in the sessionstore-backups folder.
You can check browser.sessionstore.* prefs including browser.sessionstore.resume_from_crash on the about:config page and reset browser.sessionstore prefs that are user set (bold) via the right-click context menu to the default value to make sure that Session Restore is enabled and working properly.

*https://support.mozilla.org/kb/restore-previous-session

You can also try this startup setting:

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> Browser Console (Ctrl+Shift+j), click next to <s>Code</s> the caret (>>) 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> Browser Console now.
