Firefox problem - help!

[Sue]

I just opened Firefox on my laptop, and all my tabs and history have disappeared. Including all my emails 😮

Tried to restore them and nothing happened.

There is a new folder on my desktop called "Old Firefox Data' with a load of incomprehensible (to me) files dated today.

Can anybody shed any light? 😮

Googling hasn't brought up anything useful, but I haven't searched very hard yet.

I can access emails on my mobile, but this is very inconvenient!

1. Locate Your Old Firefox Data Folder:

   • When you reset Firefox, an “Old Firefox Data” folder is created on your desktop.
   • This folder contains data from your previous profile.

2. Access Your Current Firefox Profile Folder:

   • Open Firefox.
   • Click the hamburger menu (three horizontal lines) in the top-right corner.
   • Select Options.
   • In the left sidebar, click Sync.
   • Click Recover lost data.
   • Enter your Firefox Account credentials and click Sign in.
   • Choose the data you want to recover and click Recover.
   • Your data will be restored to your browser¹

     3. Manually Copy Selected Data:

   • Navigate to the Firefox profile folder:
     • Click Help > Troubleshooting Information.
     • Under Profile Directory, click Show Folder (Linux: Open Directory; Mac: Show in Finder)¹³.
   • In the “Old Firefox Data” folder on your desktop, you can:
     • Copy specific files (e.g., bookmarks) to the current Firefox profile folder.
     • For bookmarks, look for the places.sqlite file or restore them from a JSON backup in the bookmarkbackups folder

Thanks very much for this, but unfortunately the instructions don't relate to what appears when I follow them! 

Possibly I have a different version of Firefox?

I will investigate further!
