Session History/Open Tabs Lost after CCleaner

I've been using CCleaner for years on my Dell with Windows XP. I just bought a HP with Windows 8 and installed CCleaner. Without even looking and thinking if things had changed, I ran the cleaner and it wiped out my entire FireFox browsing history (all open tabs that I needed for research). Please advise on how to get that back. I do not know how to create another profile and the internet doesn't tell me, but I've found sessionstore.jps and sessionstore.bak, I just don't know how to retrieve that information. There are no step by step directions that I've found once I've located those two files. Please help! Thank you kindly!

You would have to place the sessionstore.js file in the current Firefox profile folder.
A sessionstore.bak would have to be renamed to sessionstore.js
You can use this button to go to the currently used Firefox profile folder:

Dozens of open tabs lost! Synced them, reinstalled Windows and Firefox, set up Sync, looked up "tabs on other devices" in history - Only a third or so listed.

Dozens of open tabs lost! Synced them, reinstalled Windows and Firefox, set up Sync, looked up "tabs on other devices" in history -> Only a third or so listed.
Usually, when I reinstall Windows, I manually backup my Firefox bookmarks and open tabs, but because Sync has worked perfectly for me in the past, I didn't do it this time. I backed up all my other files and settings and whatnot from the rest of my system, then in Firefox I hit the Sync button (put in on the GUI so I see if it's syncing or done) for the last time, waited until the green rotating dot was gone, closed Firefox, shut down the system, formatted the drive and reinstalled Windows and Firefox. After setting up Sync I waited a while to make sure everything is on my system.
Then I wanted to have all the tabs and windows open as I had on the old system, so I went to the history and "tabs on other devices". I could already see from the small size of the list, that tabs were missing. I went through all of them, opened them and sorted them into windows.
-> Maybe about two thirds of the tabs I had open on my old system are gone!
Not just new tabs that might not have been synced (although the button showed sync was complete), but also old tabs (from weeks ago) that must have been synced before. Actually maybe especially or even only the old ones are lost. And the lost tabs are not just from one of the open windows, but from several.
What can I do to recover my lost tabs?
They contain important websites that I didn't bookmark yet, articles that I wanted to read, windows with dozens of tabs on a topic that I did some research for and stuff like that.
What does the green circle mean? Does it indicate that the sync is complete (to the Firefox servers) or just that the changes have been saved locally and set up for some next scheduled sync with the Firefox servers?
Further info:
I always run the newest stable release of Firefox (v19 on both systems). Old system was Windows 8 Enterprise Evaluation, new system is Windows 8 Pro. My used Sync quota is about 10 MB. I had 4 Firefox windows open with different amount of tabs in each of them, from 10 to maybe 80 with an overall amount of 150-200. Most of them weren't loaded. Firefox start is set to "load last session" and tabs are set to "load when selected". Memory usage 500 MB - 1 GB.

I have most of the items bookmarked. Having 200 - 300 tabs open saves time, since I don't have to go to the bookmarks, if the tabs are already open. One problem has been crashes, but as long as I can restore a previous session, I can still get to the data. I had quite a few tabs open when I was planning to purchase a new computer. I also follow the stock market, and the weather. I was also looking at various VIrtual Private Networking (VPN) sites. At one time, I probably had 20 - 50 tabs open, just for those. I did bookmark a few, but unfortunately lost the VPN tabs, when Firefox crashed. Even if I don`t go to a particular group of tabs very often, leaving it open is faster, especially since I will know where they are. I often put the computer in standby mode, rather than shutting it off, especially if I will remain in the same location.

Open tabs lost on exit after syncing

After selecting the new option to sync my settings with my new account, I selected to sync everything except for Passwords and History. But since then, Firefox does not save my open tabs, even though I selected that option. It does not appear to save them locally either.
Under Options -> General, I have "When Firefox starts: Show my windows and tabs from last time". I have tried restarting both Firefox and my PC (on which I just performed a fresh install of Win7 64-bit). Any new tabs I open are lost upon exiting. I did not sync my account prior to the Windows reinstall, and Firefox was preserving open tabs just fine after I had restored my profile following the reinstall. It was only after setting up the account syncing that this became an issue.

Thanks. When I tried "about:synced-tabs" earlier, I got:
The address isn't valid
The URL is not valid and cannot be loaded.
Web addresses are usually written like http://www.example.com/
Make sure that you're using forward slashes (i.e. /).
I still get that error. However, some of the other about pages do work this time.
As for the about:sync-log, I was getting errors earlier today, but now it shows success. (Nothing has changed since this morning.) Sorry, don't know how to use pastebin.mozilla.org.
I did notice earlier that all the bookmarks in my bookmarks toolbar got corrupted, and I was forced to fix them manually by deleting everything and adding them back. I'm not sure if that's related. But, again, I only get an error why trying to look at about:synced-tabs.

ICloud continues to show open tabs even after Safari quit

Since OS 10.10, when I close and quit Safari on my iMac or MBP iCloud occasionally continues to show an open tab on the other devices like the iPhone, even for several hours after Safari has been quit on the iMac. This is annoying in that one time I left it, and the iMac restarted because of a kernel panic.
This appears to be an iCloud and Yosemite problem. Furthermore, I have called Apple care twice about this, and they have been unable to find any problem with my computers.
Has anyone else had this problem, and what to do about it.

Try clearing Safari's cache : Settings > Safari > Clear Cache (and Clear History)

Firefox 4.01 no longer saves session or open tabs .. Can this be fixed ?

Simply on exiting previous versions gave the option to save open tabs so your current session was restored when Firefox reopened .. This no longer happens and is annoying .. Can it be fixed or is there some new feature ??? Thanks Warren

Firefox 4 saves the previous session automatically. 
You can use "Firefox > History > Restore Previous Session" to get the previous session. 
There is also a "Restore Previous Session" button on the default about:home Home page. 
Another possibility is to use:
*Tools > Options > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"

Major confusion re: shared history & open tabs

The subject line refers to a problem I'm having with iCloud shared history and tabs using Safari on my iPad (3rd Gen., iOS 8.3), my iPhone 4s (iOS 8.3), and Safari 8.03 on my iMac (Maverick).
The problem seems to be with my iPad. Using it, I can see the history of what I've done using Safari on the iMac and iPhone but none of what I've done on the iPad. Naturally, what I've done on the iPad does not show up in History on the iMac or iPhone. Similarly, while I can see tabs currently open on the iMac and iPhone on any of the three devices, I can only see open tabs on the iPad *on* the iPad -- i.e., I ca't see them on the iMac or iPhone.
I'm logged into the same iCloud account on all three devices and Safari is switched "on" in the iCloud preferences. I restarted the iPad. I turned Safari "off" in iCloud prefs on the iPad. (When it asked what I wanted to do with Safari data synced with iCloud -- yeah, right -- I choose to keep it on the iPad. Then I turned it back "on" and no change on the iMac and iPhone.
Any suggestions?

Firefox Sync isn't intended for the purpose of doing a "backup" and restoration, but some users have been successful using it for that. You need to have your username, password, and the '''Sync Key'''.
IMO, you are better off doing it manually. 
http://support.mozilla.com/en-US/kb/Backing+up+your+information 
That support article also cover restoration of your "information".
There's also the MozBackup program that is made for that purpose.

I can't find anything that tells how to get my saved passwords and open tabs back after syncing.

I had to have my work computer restaged. I synced my FF before I turned my computer over to tech services. When I got my computer back and downloaded FF, I signed back into sync. But my saved passwords are not showing. I have all of the items listed in the sync menu checked (passwords, open tabs, bookmarks, etc). I finally fumbled around and got my bookmarks back and I am not as concerned with my open tabs as I am with my passwords. Thanks!

These can't get your data back, but will help in the future.
These add-ons can be a great help by backing up and restoring Firefox
'''[https://addons.mozilla.org/en-US/firefox/addon/febe/ FEBE (Firefox Environment Backup Extension)]''' {web link}
FEBE allows you to quickly and easily backup your
Firefox extensions, history, passwords, and more.
In fact, it goes beyond just backing up -- It will actually rebuild
your saved files individually into installable .xpi files.
It will also make backup of files that you choose.

Tabs lost after Firefox crashed; Restore Session page doesn't load

Firefox 6.02 has been restoring previous sessions fine.
But...
When I had multiple tabs open in multiple tab groups, Firefox started slowing down. This was probably due to too many tabs opened. Eventually, Firefox crashed. Normally, under my settings Firefox launches the Restore Session page. However, this time it somehow bypassed the Restore Session page and took me straight to my home page. All my pinned tabs and tabs in tab groups were lost.
This is the second time I'm experiencing this problem in two different machines, where one was running XP and the other was running Windows 7 x64.
How do I restore my tabs? I need these tabs really bad...

You thought that, it was a bug.
https://support.mozilla.org/tr/questions/959436
BUT, For me it was not bug. it was very good for me.
i want "Well this is embarrassing...." page AGAIN.

How can I recover Firefox information (bookmarks, open tabs, etc) after "Refresh" caused profile loss?

Firefox kept hanging up. I tried Refresh button; received "almost done" message, then nothing happened. I quit & restarted Firefox, & now get message that profile is missing or moved. Used Mozilla instructions to locate profile, it was not in folder I was directed to. I now have a "Old Firefox Data" folder on my desktop.

It sounds as though the Refresh did not complete normally. But you knew that.
Since I am a Windows user, I apologize in advance if this reply is not completely applicable to your system.
Check inside "Old Firefox Data" folder for a folder with a semi-randomized name. If there's only one, that probably has your old settings and add-ons. If there's more than one, you'll want to work with the one that was updated most recently.
Once you have identified the profile folder you want to restore, here is my suggested "old profile resurrection procedure":
'''Overview'''
These are the steps detailed below:
# Create a new Firefox profile
# Remove everything from that new profile folder
# Copy in everything from the old profile folder
'''Create a new Firefox profile'''
Quit Firefox if it's running. Start up in the Profile Manager using the method in this article: [[Use the Profile Manager to create and remove Firefox profiles]].
''Notes:''
* Do not delete anything here!
* Any time you want to switch profiles, quit Firefox and return to this dialog.
Click the Create Profile button, assign a name like OldSettings, and skip the option to change the folder location. Then select that new profile in the dialog and start Firefox.
'''Open the New Profile folder in Finder'''
Firefox in the new profile should look like a factory fresh installation. Open the Troubleshooting Information page using either:
* "3-bar" menu button > "?" button > Troubleshooting Information
* Help menu > Troubleshooting Information
* type or paste about:support in the address bar and press Enter/Return
In the first table, click the "Show in Finder" button. Firefox will launch an Finder window showing the contents of your brand new profile folder.
Leaving that folder open, switch back to Firefox, and Quit/Exit. When Firefox closes, the new profile folder should be front and center, or you can activate it using the Task bar (?? or Mac equivalent).
'''Copy Old Data in Place of New'''
In that new profile folder, select all the contents and delete. Make sure you don't delete from your old folder.
Leaving that window open, open or switch over to your Old Firefox Data folder. Drill down into your old profile folder. At this level you should see a folder named bookmarkbackups among other things.
Select everything and Copy (either right-click > Copy or Command+c).
Switch to the empty new profile folder in other window and Paste (either right-click > Paste or Command+v). This may take a minute since some of the files are large.
'''Start Firefox'''
Firefox should start up in that new profile with the resurrected old profile data. Success?

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

How do i set the homepage for new tabs? when i open tabs i would like it to go to google but i cannot find out how to do this.

Opening a webpage goes to previously open tab

Hopefully the question title describes the issue
Firefox must have done an update because for example I have a browers open with 10 tabs and then open a new tab to load google.com If one of the previous 10 tabs had google.com as a page I had loaded clicked or not then it jumps to that tab instead of using what I wanted as a brand new tab
How do I go about restoring this option as I can't see a way in the options screen and I can't figure out on about:config what to change there.
Thanks again

You can remove the check mark on "Open Tabs" if this item has a tick.

After quitting a "private browsing" session, and I quit togo back to previously open tabs/pinned sites, 40% of the time, the Browser does not restore all previously open tabs/pinned apps/sites

Using HP Pavilion Dv7 with Windows Home Premium, 64bit, and only now and then will FF4.0.1 restore previous (normal) session after returning from a private browsing session, )I use the Quit Private Browsing menu item from the Toolbar right-click menu to go back).... In addition, previously Pinned sites (apps) are lost also, and all must be re-added.
Inconsistent failure and I've not been able to reliably reproduce-- sometimes (about 4-6 times in 10) it just loses all previous information.

I would add that bookmarks may be organised into folders and subfolders. You may wish to make more use of bookmarks if only to ensure you do not loose everything if your session restore becomes problematic.
Bookmarks are a bit more robust than the session restore system. Firefox backs them up automatically and you may do so manually. Possibly Firefox will behave better and faster with hundreds of bookmarks but only tens of tabs open. There is also the tabs groups, but that is something I think development has ceased on and may have similar issues to session restore / or open tabs.

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

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.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?
