Hi

Unless you have the tabs synced to another device using Firefox Sync, it will not be possible to recover the lost tabs.

I need these tabs back,quickly no excuses.Realize that I took no actions on my part for this to happen. I did not actively do anything on my part to "upgrade".

  I do not sync. Not for google, Apple, Firefox or anyone.That is for the "lazy" who value convenience over security. I can remember dozens of passwords at ease, and can get my info anytime needed.
   I need to find js file to restore from.

Ok,My tabs are still intact. This unrequested upgrade has changed everything around. The last version was fine, worked fine, was simple and good to use. If it isn't broke,why fix it? Why would I want a search box at the bottom? Why did the browser open to Private? Why do I need to sync this,that and everything? Where did all the complaints come from?

I am fine for now.As long as I am not pestered to sync.

Oh yeah, I could use an extension like "session restore". With that I am not forced to keep so many tabs open. That extension worked good and I could restore any session in the past. Somehow this was removed from Firefox a while ago and never adequately replaced.
