Unable to recover older tabs

more options

All of my 100+ open tabs suddenly disappeared from Firefox on Mac today (not sure if I pressed some button combination by mistake or what happened). When Firefox reopened, only one tab was opened which I closed/restarted Firefox couple of times. Unfortunately I don't see all these historical tabs in the History->Recently closed tabs (just the latest one after Firefox restart). Can I somewhere find and reopen all the tabs? I tried various options but no success.

Note that on Mac closing Firefox can be more complicated because you can close all open windows, but keep Firefox running with the menu bar visible or minimized in the Doc.

Make sure to use "Quit Firefox" with all windows still open, especially if you want to use "Restore Previous Session". Otherwise check "History -> Restore Previous Session" and "History -> Recently Closed Tabs/Windows".

Did you try "History -> Restore Previous Session" and possibly "History -> Recently Closed Windows/Tabs"?

Hello, I've tried both Restore previous tabs/windows, without success (just the latest tabs after the Firefox restart appear there). I could not find Restore previous session under History, the item is not there.
