Only one of my two windows was restored after I restarted Firefox (150.0) in Mac OS 26.4.1, and "Restore previous session" is greyed-out. Is there any way to reopen the missing window?

Is there any way to reopen the tabs from that missing window? "Recently closed windows" only shows the last 3 tabs in that window. I've tried restarting Firefox 3-4 times, and rebooted my Mac, with no success. The reason I originally restarted Firefox is because it was suddenly working very slowly. The window that did open has about 30 tabs; the one that didn't open only had about 15 tabs.
