Why do I get a strange error message when Firefox crashes? (Part 1)

Episode 972 (49:29)

Steve from California

Steve has a PC and Mac. When he uses Firefox on the Mac, however, he gets an error message whenever the browser would crash. Leo says that message is telling him that when he reopens the browser, the tabs and windows he had open will come back up when he relaunches the browser. He can disable this setting if he doesn't want it to do this.
