Re-opening closed Firefox opens all the tabs and windows

[mbielski]

Currently, we have 3-4 Firefox browser windows open. We close them because we want to perform a system update or restart the computer. After restarting the computer and opening the Firefox browser, clicking CTRL+T (to restore closed tabs) only opens one of the several Firefox windows, restoring its tabs. The remaining windows and tabs that were open are lost. Only one window remains, seemingly chosen at random, as I don't have the option to select a specific closed window to restore.

It would be great if, upon reopening Firefox and restoring tabs (CTRL+T), ALL WINDOWS and TABS were restored, not just a single chosen one. I have a feeling that this functionality used to exist, as I've frequently restarted my computer and closed Firefox, only to reopen it after the restart without losing any open tabs.

This is not due to computer parameters; the computer is powerful enough to handle 20 open tabs simultaneously across multiple monitors.
