restore previous session missing from menu

My previous session didn't automatically reopen when I restarted firefox. When I went to the help section, it told me to click "restore previous session" from the menu, but I don't have that on my menu. The example shows it after "new private window", but my menu has "zoom" in that spot. I noticed that the "sync" isn't at the top of my menu either. I had this problem once before, but it was long ago, and I don't remember the solution. Hope that I'm describing my problem well enough. Frustrating for a senior, trying to stay safe.

Make sure you do not run Firefox in permanent Private Browsing mode (Always use Private Browsing mode; Never Remember History).

  • Options/Preferences -> Privacy & Security
    Firefox will: "Use custom settings for history"
  • remove checkmark: [ ] "Always use Private Browsing mode"

In case you use "Clear history when Firefox closes".

  • do not clear the Browsing History
  • clearing "Site Preferences" clears exceptions for cookies, images, pop-up windows, and software installation and exceptions for passwords and other website specific data
  • clearing "Cookies" will remove all selected cookies including cookies with an allow exception you may want to keep

I really don't understand your answer. Are you saying that any update to Firefox does this now? I didn't change anything, but is it something I need to opt out of? I'm starting to feel like I should write down each tab in a notebook. I'm sorry that I'm not smart enough to follow what you're saying.

If these are not available -- hidden or grayed out --

  • "3-bar" menu button > Restore Previous Session
  • (menu bar) History > Restore Previous Session

-- Firefox might already have restored your session. Check one of these:

  • "3-bar" menu button > Library > History > Recently Closed Windows
  • "Library" toolbar button > History > Recently Closed Windows
  • (menu bar) History > Recently Closed Windows

If that doesn't help...

Firefox creates numerous session history files, but because session history is only for the immediately previous session, it is unfortunately too easy to lose it. Could you start by making a backup of your existing session history files? Here's how:

Do not exit Firefox, or if you closed it, don't re-open it.

(1) To open your profile folder...

If Firefox is still running:

You can open your current Firefox settings (AKA Firefox profile) folder using either

  • "3-bar" menu button > "?" Help > 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 "Open Folder" (or "Show in Finder") button.

If Firefox is closed:

Type or paste the following into the Windows Run dialog or the system search box and press Enter to launch Windows Explorer:

%APPDATA%\Mozilla\Firefox\Profiles

In that folder, do you see a semi-randomly-named folder? If so, click into it. If you find multiple such folders, find the one that was most recently updated.

(2) Copy out session history files

In your profile folder, double-click into the sessionstore-backups folder. Save all files here to a safe location such as your Documents folder.

(3) What files did you find?

The kinds of files you may find among your sessionstore files are:

  • recovery.jsonlz4: the windows and tabs in your currently live Firefox session (or, if Firefox crashed at the last shutdown and is still closed, your last session)
  • recovery.baklz4: a backup copy of recovery.jsonlz4
  • previous.jsonlz4: the windows and tabs in your last Firefox session
  • upgrade.jsonlz4-build_id: the windows and tabs in the Firefox session that was live at the time of your last update

Could you take a look at what you have and the date/time of the various files to see whether you think any of them would have the missing tabs?

To preview the contents of a file, you can drag and drop it onto a tool on my site, then click Scrounge URLs:

https://www.jeffersonscher.com/ffu/scrounger.html

If you don't get a list within 15 seconds, that probably means the script is caught in a loop. You may need to close the tab to avoid a tab crash and then try again in a new tab.

If you get a useful list, use the Save List button to archive it as a web page of clickable links for future reference, in case no other approach is successful.

It's only showing me closed tabs or windows from today. At this point, I'm looking back over my history from the last couple of months, but it's not much help. I guess I'll bookmark everything as I go along now. Thanks for trying, I appreciate the effort.
