Tabs disappear on restart on Mac; history is preserved though

Answer seen before was to ensure that the selection to start where left off (done) and that history not deleted (done)

Is Firefox creating a file sessionstore.js in the Firefox Profile Folder?

It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.

If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.<br />
Deleting sessionstore.js will cause App Tabs and Tab Groups and all open tabs to get lost, so you will have to create them again (make a note or bookmark them).

How to restore search history tabs; disappeared after I cleared search history; can't restore tabs!

I recently cleared my search history - I deleted everything - but now my search history tabs (that were generated after each search) have disappeared, and I can't restore them no matter what I do. Also, under "History", "restore previous session" and "recently closed windows" are gray, and so can't be selected. I've "reset" Firefox to "default" status twice to no avail...help! I need those tabs!

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

Firefox occasionally crashes, after restarting it app tabs disappear. 8.0.1

From time to time, Firefox crashes.
When I open Firefox again, my app tabs disappear.
The problem is that I had more than 50 app tabs, and I really need them back, as I don't recall some sites' titles or addresses and I can't find them in history.
How can I restore or at least make sure that it doesnt' happen again?
If it is not restoreable, is it legal to change Firefox core files?

My problem is not necessarily when Firefox crashes, but when I have two windows open, one with my tabs and one plain one. If I close the one with my tabs first, and then the plain one, when i restart Firefox reloads only the plain window, and I cannot get my tabs back. This has happened to me numerous times and is highly annoying. I don't have 50 tabs like Mirac7, but it still frustrates me. Can't these be linked to my profile, instead of just the particular window I have open at the time?

Firefox 4 mac. no save tabs when exiting/restarting

I just upgraded to firefox 4 on my mac.
I have looked in the preferences for the option to save tabs (multiple tabs) when exiting / restarting firefox.
I have found info on this for windows but not for os x.
I love and use this feature extensively. How do I get it back?
Thanks in advance

App tabs and Tab Groups (Panorama) are stored as part of the session data in the file sessionstore.js in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder]

Make sure that you do not use [[Clear Recent History]] to clear the "Browsing History"

All of a sudden, can't find the firefox tab(with arrow)to view bookmarks, history,etc

'''bold text'''
At the upper left corner there used to be a firefox tab with an arrow. When clicked, we could find our history tab, bookmark tab,etc. It is now missing.

Please give the following a try, in order, until resolved:
Turn AirPort (OS X) on & off: You do this via the AirPort icon on the OS X menu bar.
Make sure your internal AirPort card's firmware is up to date: You can check by going to the Software Update menu.
Delete and recreate your wireless connection in System Preferences > Network.
Create a new Network Location in System Preferences > Network. Log off / log on, and then, try using the new location.
Change the DHCP auto setting to manual on the Mac via System Preferences > Network > Wireless. Manually enter an IP address outside of the DHCP range in use. For example if your AirPort is providing IP addresses in the 10.0.1.2 - 10.0.1.200 range (the default), choose 10.0.1.201 for your Mac. Also enter the appropriate DNS servers on the DNS tab.
Flush the DNS cache: Lauch Terminal and enter the following: dscacheutil - flushcache
Reset the PRAM: Reboot your Mac and hold down the Command+Option+P+R keys during restart until you hear a second chime, then let the Mac boot as usual.
Delete the wireless configuration files: Go to ~/Library/Preferences. Delete com.apple.interntconfigpriv.plist and com.apple.internetconfig.plist. Reboot your Mac.
Delete your Home directory's SystemConfiguration folder: Go to /Library/Preferences/SystemConfiguration/. Move the SystemConfiguration folder to the desktop. Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder back to it's original location.)
Finally, try resetting your Mac's System Management Controller (SMC): Shutdown the MacBook Pro, remove the battery, disconnect from power (if connected), and then, hold down the power button for 15 seconds. Replace the battery, reconnect to power, and then, reset the PRAM (per the previous step).

App tabs and web page tabs not saved when Apple Mac is powered down

Using Firefox with Apple Mac running OS X v 10.7.1 and Parallels 6, and Windows Vista as a virtual computer. Have Firefox 6.o installed on the Mac and Firefox 6.0 for Windows installed within Microsoft Vista running under Parallels 6 as a virtual machine.
Issue 1) Within Mozilla on the Mac whenever I power down and restart the computer all my app tabs and web page tabs are lost except for my home page, even though I have set up Firefox preference to remember my open web pages/tabs.
Issue 2) Within Firefox running within Vista on the virtual machine my web pages are remembered but I cannot figure out how to create a app tab.

Tabs are only saved if you close (Firefox > Quit) the Firefox application while those tabs are still showing. If you close a window and still have the menu bar visible then you wont reopen already close tabs. You may need to be able to reopen the three last closed windows via History > Recently closed Windows.

-> Tap ALT key or press F10 to show the Menu Bar
-> go to Tools Menu -> Options -> Privacy -> History section -> '''Firefox will: select "Use Custom Settings for History"''' -> REMOVE Checkmark from '''"Permanent Private Browsing mode"''' -> place CHECKMARKS on:

4a) Accept Third-party Cookies -> under "Keep Until" select "They Expire"
-> REMOVE CHECKMARK from CLEAR HISTORY WHEN FIREFOX CLOSES
-> Click OK on Options window
Check and tell if its working.

I had about 17 tabs open on my browser. I clicked a link to open another one and when the tab opened the other tabs disappeared. What happened here?

I had 17 tabs open. When I clicked a link to open a new tab all the other tabs disappeared. I thought a new window had been opened instead, but this is not the case there is only one window open on my mozilla browser. If I try to close the window I get a message that says there are 26 tabs opened, I opened 9 more tabs. Can anybody tell me what is going on here or how I might figure this out?
Also, when I close a tab and try to reopen the tab using the right click menu, the 'undo closed tab' menu is disabled. What happened here? Can anybody tell me how to re-enable it?

I've seen some occasional glitches with windows losing the toolbar area, but not one that disturbing.
If you click and drag down on the 18th tab enough to tear it off into a new window (and possibly the same for the other newer tabs you opened), can you get the 17 tabs to re-appear in the first window? If not, I'm not sure there is a way to mend the window. If it's NOT a private browsing session, you might have to use Firefox > Exit (or File > Exit) and restore your session to get a working window. That won't work with a private window...
As a backstop, you might also right-click a tab in the window > Bookmark All Tabs before ending your session. (Because session cookies and other transient data are not preserved when you reload bookmarks, this isn't as effective as restoring a session. On the other hand, bookmark storage is less fragile than session data storage.)
Regarding Undo Close Tab, are the closed tabs listed on the History menu under Recently Closed Tabs? If so, that context menu item definitely should be enabled.

When i updated OS X update to 10. 10.2 and iTunes to 12.1 and restarted my mac, safari got messed up

I updated my OS X and iTunes today and when I restarted my mac, safari got messed up. No matter how many times I change the preference of the new windows and tabs to favorites and remove the homepage site, it always get back to what it was-- homepage for both and search-quick.com for the homepage site. I can't open a new tab/window with the favorite--and it's very annoying since it opens with the search-quick.com. I've never installed search quick program, and I can't get rid of it. On the preference, the google is set to my search engine but whenever I search something it uses that search quick site. I don't know how to get rid of it and I want to remove it so bad. The biggest issue is whatever I click, the useless ads (mackeeper, justcloud, seniorsoulmates, McAfee, etc) keeps popping up on the new tabs. Literally, it pops up whenever I click something. It's driving me crazy- what should I do?

Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

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

Outlook email account disappeared after restarting

Today my husband shutdown and restarted his Mac Pro as it was running slow and he hadn't turned it off for a few days. When he reopened Microsoft Outlook the entire email account was gone. He tried going back into Time Capsule to last night but nothing would work and then all the other Office programs disappeared. Apple support could only help so much, then they said to ring Microsoft. No help there, they put us onto Log Me In Rescue support and we have paid for them to try and fix it but they are having no luck at all.
They said our system has been hacked which we didn't think could happen on a Mac. We only had POP emails set up not exchange. Can anyone offer any support at all.
Cheers in advance

I went back to him and this morning we had checked in the identities folder as you suggested and there was nothing in there. Checking again tonight there are files in there, but what we do with them we don't know. It could be from when to remote help people were reinstalling tonight.
What we have just discovered, and this was not there this morning, he went into Finder and All my files. It breaks things into different sections. There was a section saying Mail and messages and there are over 13,000 items in there and all his contacts are now there. We are not sure how they got there or how to get it back to Outlook. He went to do the rebuild but there are two identity options, and we are worried about making a mistake. Not sure what is going on.
I have spent so much time in these forums and others trying to help and I am a person that is shocking with computers. I thank you for your help so far. Still playing with it and I booked him a session at the apple store tomorrow as well.
I just have to say how appreciative I am of the time you have given in trying to suggest solutions to our problem. There are so many people that just won't help.
Cheers,

Every time I open a new tab my older tab disappears.

Every time I open a new tab my older tab disappears. The old page is still open, but I cannot see it. How do I fix this?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

I followed the instructions for making an APP TAB and succeeded BUT everytime I close Firefox, the app tab disappears upon re-opening. Can someone help please? I held the control button plus I clicked and selected the "Pin..as app tab".

As my question asks, I followed instructions for creating an APP TAB for my web mail account, and succeeded but each time I close and re-open Firefox, the app tab disappears. Can someone tell me what I am doing wrong please?

For better or worse, I think it's part of the design for the app tabs to be window specific. I know my first reply didn't solve your problem, but that was one way that worked for me to get the app tabs back when I restarted Firefox. Also I noticed the tag for this post is Firefox 4. I've only tried it with Firefox 5.
I agree with you that the way it's working isn't ideal. For the time being, I've stopped using the app tabs. Maybe they'll fix/improve it soon.

After typing a sudo command on terminal how do you save it so you dont have to keep giving that same command every time I restart my mac??

I have a 45mb/s internet at home and my youtube videos load extremely slow, after reading many blogs and empting my cache cleaning my history I stumble across a post that told me i had to block two IP's on the terminal using this two commands: " sudo ipfw add reject src-ip 173.194.55.0/24 in" and "sudo ipfw add reject src-ip 206.111.0.0/16 in" that it should help. After I did that and restarted the mac those commads are undone. Is there a way to save thos commands tipped in the terminal??

Open the AppleScript Editor in the /Applications/Utilities/ folder and paste in the following:
set thepass to text returned of (display dialog "Your administrator password is needed." default answer "" buttons {"Cancel", "OK"} default button "OK")
do shell script "ipfw add reject src-ip 173.194.55.0/24 in" password thepass with administrator privileges
do shell script "ipfw add reject src-ip 206.111.0.0/16 in" password thepass with administrator privileges
Save it as an application and add it to the list of login items for your user account in the Users & Groups pane of System Preferences.
