Body

The screenshot shortcut for Firefox is documented here, andn is CTRL+SHIFT+S.

Depending on the context of where you are on GitHub, this shortcut will instead attempt to download/save the file instead.

Unsure if this should be classified as a "Bug" per-se, but thought I would raise it anyway.
