I accidentally put one of my tabbed groups into hibernate. HOW do I get it back? There were about 10-12 tabs open in there and I have NO idea how to get them back! This has happened before but it was no biggie, this time there were some important tabs that I do not remember what they all exactly were! Somehow I clicked the tabbed group and bunch of "zzz's" appeared and then when I went to click off, my group disappeared! Does ANYONE know how to correct this?

What do you mean with that you "hibernated a tab group"?

Did toy delete (remove) this tab group?

App tabs and tab groups are stored in the sessionstore.js in the Firefox profile folder.

You can try to restore a previous version of this file to see if that restores the lost group.

  • Right-click this file in Windows Explorer: Properties > Previous Versions

You can use this button to go to the Firefox profile folder:
