Firefox won't automatically open tabs from my previous session.

I have literally tried everything, from the general option menu to directly using about:config to fix this problem. It happens all the damn time, and after dicking with it, I can usually fix it, but this time, I cannot get firefox to restore tabs from my previous session. I have it set to restore my previous session in the general options menu, it warns me when I close multiple tabs, private browsing is disabled. I don't know what else to do. I've scoured this site and tried every solution I could find, but none of them are working.
Firefox had frozen, so I had to ctrl/alt/del to close it, and when I restarted it, my session was gone forever. I've done this before and it's never dicked with the settings. I realize that there's a 'restore previous session' option in the history, but I want it to load automatically.
It's getting really bothersome with the amount of times firefox has done this.

Go to''' Tools'''
then '''Options'''
In privacy choose '''Remember History'''
Then go to
''General Tab''
At the start up drop down menu when firefox starts select
'''show my windows and tabs from last time'''
That should fix things

Firefox 4 opens multiple windows (15-25) when opening and only once in a blue moon will remember the tabs from the previous session in the first of the multiple windows.

When I open Firefox 4 from either the icon or from a link from e-mail or some other place, multiple windows open up. Usually between 15 and 25 of them. I'm running Windows 7 Ultimate on both my laptop and desktop and have the same issue with both. I tried disabling the plug-ins one by one since they were all up-to-date, to no avail. My laptop has an upgraded version of Windows while my desktop has a clean install. I tried uninstalling Firefox 4 and going back to 3 and then the same thing started happening withe v3 when it wasn't before. Only sometimes, on rare occasions, will the first window that opens have my tabs from the previous session. Most times all the windows have one blank tab. The first one I can tell 'cause it does not have the orange Firefox menu button (since I'd chosen to show the Menu Bar) while the first window shows the menu bar. The troubleshooting info is from my laptop only.

Unless the schedule it's running on is every single time I open Firefox (including closing it & reopening it right away), I don't think that's the case. Also, I don't have any of these issues on the PC I switched back to v3.6 on. That one runs smoothly whether I run Ccleaner, registry optimizers, clear the cache & history or whatever. I thought after you first gave me the answer of deleting the session files that they must've got corrupted during the upgrade, but it seems that v4 just doesn't do a good job of retaining or maintaining those files without getting them corrupt or something.
If this is not an issue with everyone & I'm having it on both my PCs, then v4 has an issue with something that I install on my PCs that, I guess, many others don't although I don't know what that could be and I use everything I install or have running. So, I'm just going back to what works without having to dismantle my config one prog at a time to try to find what v4 may be finicky about.
By the way, I did check & couldn't find any cleaners that run automatically on my PCs.

Firefox won't remember the tabs from when I closed it out last.

I signed out of my laptop to go and do something else, and when i rebooted it, and clicked on firefox it came up with my homepage, Bing, instead of the five other tabs I had had on it. As a test, I pulled up two different tabs, Facebook and DeviantArt, and I purposefully closed it again, hoping it was only a minor problem. When I clocked back onto it, it was Bing again. I've gone to tools, options, and looked under the start up settings, and it says it will remember tabs from the last session, but it isn't, and when i look under history, it only says Bing, even though I've been using firefox for over a year and i have more history than that. It's a very annoying problem since i just got used to the layout, and i don't like internet explorer, so i would very much appreciate if someone could help with my problem.
== This happened ==
Every time Firefox opened

If you use [[Clear Recent History]] in Firefox 3.5/6 or [[Clearing private data|Clear Private Data]] in Firefox 3 to clear the 'Browsing History' when Firefox is closed then restoring tabs from the last session (e.g. "Save & Quit" or "Show my windows and tabs from last time") doesn't work.
Make sure that you not run Firefox in [[Private Browsing]] mode.
In Private Browsing mode some menu items are disabled (grayed) and features like visited links and disabled and not available.
You are in Private Browsing mode if you see "Tools > Stop Private Browsing", possibly grayed.
You enter Private Browsing mode if you select: Tools > Options > Privacy > History: Firefox will: "Never Remember History"
To see all History settings, choose: Tools > Options > Privacy, choose the setting '''Firefox will: Use custom settings for history'''
Uncheck: [[ ] "Automatically start Firefox in a private browsing session"

Every time I launch Firefox 4 it opens 3 or 4 blank windows, no longer opens the tabs from the previous session and does not show my bookmarks sidebar.

I have to manually close the extra windows and restore the tabs from the previous session, and reopen the sidebar. In disgust I uninstalled Firefox 4 and reinstalled 3.6. Everything works fine in 3.6. Looks to me like Firefox 4 has many major bugs and is not yet ready for prime time. I'll stay with 3.6 for now.

When the browser opens, I want to be able to open all my open tabs from the last session or have a blank home page if there weren't any tabs to reopen. How do I set the homepage to do that?

When Firefox starts up I would rather have a blank page for the homepage if I didn't have any tabs from my previous session to open up. There doesn't seem to be an option for this. The choice is to either reopen last session tabs OR blank page but does not seem to allow for "if no last session tabs, then open blank page" If it does, then please tell me how.

It would seem if your choose "Show my windows and tabs from last time" '''''and''''',
*when you last closed Firefox, you had no web site open (just a blank tab), that it would open just that blank tab
*when you last closed Firefox, you had one or more tabs/web site open, that would allow you to "Restore Previous Session"
#Have you tried that?
#If so, what is happening in each circumstance when you reopen Firefox?
'''Restore Previous Session''' 
Open tabs are automatically saved when closing Firefox beginning in Firefox 4. To open your last session, after Firefox starts, click History > Restore Previous Session. For this to work
#You must be remembering history (Options > Privacy > Remember my browsing history).

Installing Firefox 4 changed my tabs options so when I start load it starts a new session. I want to recover my tabs from my previous session. How?

Installing Firefox 4 changed my tabs options so when I loaded, it has started a new session and not loaded the tabs I had open when I closed my last session.
I want to recover my tabs from my previous session. Possible?
My previous session had been open for over a week so this history is basically useless as it's cluttered with thousands of pages.

# Press Alt+T
# Click on Options
# Go to General Panel
# Under the category When Firefox Starts select "Show my windows and tabs from last time"

Can I import "Open Tabs" from a previous installation?

So i'm building a new computer for my friend's dad, and he's going on about how he needs his old tabs back because he never closes his tabs and he has dozens open and it helps him keep track of what he's doing.
Is there any way to import what was going on last session into a new installation of firefox on a diffrent computer. We have the hard drives but the PC is dead, so we only have access to the files in the folders.
Thanks in advance for the help.

hello, you can try to restore his old profile from the former harddrive - this should contain all his personal data including any open sessions...
[[Back up and restore information in Firefox profiles]]

Helllo I cannot activate the setting in the options panel get Firefox to restore the tabs from the previous session. The option is grayed out. What can I do?

When I start Firefox itt will not restore the tabs I had open during shutdown on the last session. This used to be an option when working on something in order not to have to leave the pc on over night. Now the option under Firefox/Options/General: On Firefox Startup: "Restore the tabs & Windows that were open in the last Firefox session" is grayed out, so that I cannot select it.

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

Why doesn't firefox save my windows and tabs from last time ?

i have gone to tools, options, then under the general tab i set firefox to start up : I set show my windows and tabs from last time.
When i closed firefox and then started it again it didn't work.
What can be done to resolve this issue please?

Make sure that you do not use "Clear Recent History" to clear the "Browsing History" when Firefox is closed because that prevails and prevents Firefox from opening tabs from the previous session.

If you use cleanup software like CCleaner then make sure that Session is unchecked in the settings for the Firefox application.

Safari keeps opening tabs from last session and Bookmarks and favorites. help?

I recently reset my macbook due to Adware on it. Everything was working fine until yesterday.
I would open safari up and all the tabs from the previous session were open,not only that even the tabs from the session before the previous were open as well. sometimes the pages won't even load??? Ive looked through some of the tabs and a lot of them are my favorites and bookmarks. Im a college student and I depend on my computer a lot please help me. Im really frustrated I can't use the internet. HELP?

What are your settings here? If you have them set to Open with Favorites instead of Empty Page, that means Safari is loading all of your Favorites every time you open a new window or a new tab.
On the first option, is it set to open with "A new window" or "All windows from last session"? That would explain one issue.

How do I get Safari 7 to open with my tabs restored from my previous session?

I have a new MacBook Air running Mavericks. How do I get Safari to open with my previous tabs restored. I used to be able to find an option in Preferences that said when you open a new window open with the tabs from my previous session. That is no longer available to me.

I don't have that option in my general preferences. Even though I have Safari set to open with all windows from last session, it doesn't. I also think its very slow

How do I access open tabs from other devices in Firefox 4 for desktop (windows version)

I want to see the open tabs from other devices but I can't find how to access it.
Where do I find them in firefox 4?
I use the windows version.
Thank you!

This is for all versions (image attached below):
1. In the top navigation (you might have to press the ALT key to reveal the menu), navigate to '''History - Tabs From Other Computers'''
2. Alternatively; open a new tab and type '''about:sync-tabs''' then press enter.
NB: When you open a tab in the 'Tabs From Other Computers' window it '''WILL NOT''' remove that tab from the other device.

Can't open tabs from previous session (after Firefox regularly closed)?!

Regularly closed firefox 36.0.4. and shot down computer (Windows 7 Pro 64-bit).
On next start, Firefox doesn't open tabs from previous session (altought it is configured to do this) !?!?!?
I lost about 30 tabs!!
Very, very frustrating!!!
Think to finish using Firefox forever!!!!!

Don't exit Firefox! Or if you already did, don't start it back up again!
''If Firefox is running:'' 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 new window listed various files and folders. For best results, change the view to "Details".
(''If Firefox not running, get to this folder by pasting the following in the Run box on the start menu and pressing Enter:'' %APPDATA%\Mozilla\Firefox\Profiles ''and then double-click into the most recently updated semi-randomly-named folder you find there.'')
In the window that launches, scroll down and double-click into the '''sessionstore-backups''' folder. Save all files here to a safe location, such as your Documents folder, so Firefox doesn't overwrite them. We may be able to use them to recover your lost tabs.
Also, if you return to the main level of the profile folder, you may find some sessionstore files. Copy those to the safe location as well.
Could you report back on what you found?
Note: If Windows hides the .js file extension from you, you can change a setting so that you can see all file extensions (this helps when renaming files). This support article has the steps: http://support.microsoft.com/kb/865219 or http://windows.microsoft.com/en-us/windows/show-hide-file-name-extensions
The kinds of files you may find among your sessionstore-backup files are:
* recovery.js: the windows and tabs in your currently live Firefox session (or, if Firefox is closed, your last session)
* recovery.bak: a backup copy of recovery.js
* previous.js: the windows and tabs in your last Firefox session
* upgrade.js-''build_id'': the windows and tabs in the Firefox session that was live at the time of your last update

After crashing, Firefox is not re-openeing saved tabs from my last session, but is re-opening tabs from a session over a month old. How do I find my saved tabs?

Firefox opens with my tabs from my last session even though my options are set to show my homepage on start up.

Whenever I open Firefox, it starts up with my tabs from my last session even though I have "Show my homepage" selected in my options for when Firefox starts.

I first thought that i had the show my homepage option selected but when i checked it had changed. Here is how to change it back....
1. Go to FIREFOX
2. Select OPTIONS under the OPTIONS tab
3. Under general make sure you have the 'When firefox stats: show my homepage'
selected
Then restat firefox

Firefox won't automatically open tabs from my previous session.
