App tabs lost after shut down and I have to redo them after every shut down any idea as to why they dissappear?

I use the app tab feature. After I have made the app tabs they disappear when I reboot the computer after shut down. So each time I have my frequently use sites as app tabs they disappear after shut down and reboot? Any Ideas as to why? I use Firefox 5, on a Windows 7 Home Premium machine. I use the addon "Too Many Tabs" would that conflict with the "App Tab" feature?

App (pinned) tabs and Tab Groups (Panorama) are stored as part of the session data in the file sessionstore.js in the Firefox profile folder.

Make sure that you do not use Delete browsing, search and download history on Firefox 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.

This answer didn't work in my situation. I checked my setting and all were set to allow tabs and browsing history to be saved. I reset my app tabs and they disappeared again after shut down. I use Advanced System Care 4 Pro as my maintenance program and run it once a week. I changed the setting in System Care 4 to not clear history. I have something going on though. This started after my install of Firefox 5. I didn't use app tabs before installing Firefox 5 but I did have open tabs which were always there. I will keep trying to correct this, as now it has become a challenge. Thanks for the post though I did learn a few things and did consider it helpful.

I have also just checked some settings In the Orange Firefox tab at the top in the History section the Restore Previous session, Recently Closed Tabs, and Recently Closed Windows, are all grayed out. I also opened several tabs at different websites and after I rebooted they were gone. I have my setting set to Show My Windows and Tabs From Last Time. Maybe a reinstall of Firefox 5. I will try to reinstall 5.

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

  • https://support.mozilla.com/kb/Private+Browsing
  • You enter Private Browsing mode if you select: Tools > Options > Privacy > History: Firefox will: "Never Remember History"
  • To see all History and Cookie settings, choose: Tools > Options > Privacy, choose the setting Firefox will: Use custom settings for history
  • Deselect: [ ] "Permanent Private Browsing mode"

I have checked all setting and even reinstalled Firefox 5 but still have the same problem. I never use private browsing or any other of the browsing history setting as I do have certain sites that I always leave tabs open. I can't leave any tabs open and shut down without having to reenter them after start up. I didn't have this problem with version 4 or any version before that.

Right now, for this problem as I have it, the solution is to make sure you close the window with the app tabs last. It seems that Firefox will count the lack of app tabs on the last window closed the same as removing the app tabs manually.

Given App tabs don't cross windows currently this doesn't surprise me. If you use multiple windows often, for now at least, this feature will only be useful if you want to minimize tabs.

I will give this a try. I also use Too Many Tabs so guess I will just go back to using them and adding a page or two to my Home page button.

I have the same problem plus each time I reboot I lose ALL of my history. Following above suggestions, I have checked all of my settings. Using Tools>Options>Privacy I have it set to Remember History. But it "forgets" all history as soon as I close Firefox. Please keep working the problem. Thanks.

This is a Firefox 5 issue. In Firefox 4 they worked beautifully. I loved them. They saved me a lot of time. I hate it when you "fix" something that worked!
