Dear Mozillians,
I have saved some sessions using add on called Session Manager. But it is now a legacy Extension and I have no longer access to my old sessions that I saved past several months.
I want all the saved sessions back but I have no Idea how to restore them.Also I have installed alternate add on “tab session manager”.
Thanks

Hi Taneja, Tab Session Manager has an import feature, although I haven’t tried it myself.
Session Manager stored its files in a folder named sessions in your Firefox Profile folder:
https://support.mozilla.org/kb/profiles-where-firefox-stores-user-data
If Tab Session Manager cannot import them, I have a tool to extract their contents to a web page of clickable links.

The latest version of the Scrounger assumes a recent JSON format, so if it doesn’t work on a Session Manager file, try the older version:
Hello @jscher2000
Thanks for helping,
I was using Session Manager, I had saved almost 20 sessions manually (so as to see them later).
On the addon website it clearly states that all of the saved sessions would be in “Sessions” folder in profile (There is no such folder), I have a folder named “sessionstore-backups”
I tried using the tool you mentioned for extracting the contents (sessionstore-backup folder) but that was not what I am looking for.
Now I am thinking to downgrade firefox so that legacy extension (session manager) starts working & after saving all the content from extension I’ll update firefox to latest version again.
Please kindly suggest it would work for me or not.
Thank You
Taneja
The sessionstore-backups folder contains files created by Firefox itself. Did your Firefox perform a Refresh at some point? That would move your old profile folder (including the sessions folder) to your desktop inside an Old Firefox Data folder. If you don’t have that, then perhaps you have backups??
Where is it going to find the old data? That is the first step, finding that sessions folder.
I got it, since the sessions folder is missing I can never get my old data back 
I’ll take care from next time onward 
Thank you

What is your OS?
On MacOS, you could look at Time Machine backups of your profile folder.
On Windows 7-10, you could check old restore points using a program like one of the following that allow you to browse and export out files from an old snapshot of your profile folder – DO NOT USE system restore as that will probably cause more data loss:
You probably need to set Windows to show hidden files and folders in order to get to your profile folder in the restore point: https://support.microsoft.com/en-us/help/14201/windows-show-hidden-files
Step back one level in the file system, to the directory (folder) that contains your profile directory.
From the ‘parent’ view: is there just one profile directory? Or are there sibling directories?
