Reproduced on Linux in Firefox 39.0.3 as well as Nightly build of 24/08/2015 (including safe mode, clean profile).

The page has a keydown handler on document which listens for this key among others:

document.onkeydown=function(e){e=e||window.event;if(e.keyCode==123||e.keyCode==18){return false}}

The tools can still be opened via menus, so it's just the key shortcut that is affected.

See also bug 1052569, bug 380637. Though I haven't noticed F12 or Ctrl+Shift+I there.

F12 opens the developer tools for me with Firefox 84.
