Not only Firefox. Cmd-/ is also a very common "toggle line comment" shortcut. I think it's the default on Sublime and IntelliJ, and any editor that offers a "Sublime compatible" preset (like VS code) imitate that. Of course, such a shortcut broken out-of-the-box for any keyboard layout that lacks a / key.

Yeah, Sublime copied this shortcut (like most of its features) from TextMate, and it has since spread widely.
Amusingly, TextMate's author and many early users were European programmers with US-ANSI keyboards (because the various European layouts are just too painful for writing code in ASCII-based programming languages).
