I would like to restore the warning of closing multiple tabs before closing. I am on Firefox 80.0.1. There is not box under Menu > Options > General tab of "Warn me when closing multiple tabs". When going into about:config and searching browser.tabs.warnonclose the value is true.

I'm not sure where else to look to restore this option.

Can anyone Help? Thanks

This warning is connected to session restore and you are only warned if you close more tabs than session restore can restore. See about:config => browser.sessionstore.max_tabs_undo

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
