I'm using Firefox since 6 years and I don't see a shortcuts customize page. I love you're app and I can't tell myself that you haven't turned on this feature. SO WHERE IS SHE ??? (I do this post because I add the extension "Multi Account Container" and they add the shortcut CMD SHIFT + to open new Personal Container. But I use CMD SHIFT + to zoom on my window, so when I want zoom he open new tab.) Thanks you
