User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:64.0) Gecko/20100101 Firefox/64.0

Steps to reproduce:

at the moment the shortcut ctrl+w is reserved (key_close and key_closeWindow in This is pretty annoying for webapplications with custom keybindings like codemirror-editor (vim-mode) or browser games.

Actual results:

JS applications are not able to overwrite the keybinding. So Crtl+w always closes the focused tab.

Expected results:

It should at least be possible to overwrite the keybinding by addons like Shortkeys or to patch the after building.
