Hi, Firefox periodically saves backups of your saved tabs. There's no guarantee that the exact set of tabs you are looking for has been backed up, but you could try looking to see if it is: 1. Go to about:profiles. 2. Find the "default" profile in the list, and look for the "root directory" column. 3. Click on "open folder". 4. In that folder, find the "sessionstore-backups" folder and open it. 5. Inside that folder, you should see a series of files. Open this website: https://www.jeffersonscher.com/ffu/scrounger.html, and drag each file onto the area labelled "drop file here". After each file, click on the "Scrounge URLs" button to get a list of all the tabs that were saved in that file. Once you've found the links you want, you can ctrl+click on each link to open it. Hope that helps!

Sorry for the delay, but thanks!
