All the application windows I had opened on my Mac, closed due to a security related update. Now Firefox isn't showing any of my tab groups from before and also there's a weird behavior when you click on the Firefox icon, it opens a new window that is small, but when you do file > new window it also opens a window but full sized. I tried creating a new tab group and the second approach of doing file > new window is showing the tab group in the tab group menu, but the window created by doubling clicking the icon doesn't show it.
