Firefox updated my browser yesterday and when I switched on my computer this morning, my"recently closed tabs" was blanked out and now I cannot get my old Firefox back again.

Sorry to hear about this problem. Are either of these available and, if so, do they do anything:

In case your session wasn't restored automatically:

  • "3-bar" menu button > History > Restore Previous Session
  • (menu bar) History > Restore Previous Session

In case a different window has the missing tabs:

  • "3-bar" menu button > History > Recently Closed Windows
  • "Library" toolbar button > History > Recently Closed Windows
  • (menu bar) History > Recently Closed Windows

Did you notice any other changes to Firefox when this happened?
