disable firefox's control+w

Question

How can firefox's keyboard shortcut control+W, which closes a tab, be disabled? There's nothing in about:config under browser.tabs.

(When in a web session that is a virtual host's console, that's the venerable Linux keystroke to delete the last word you've typed. Deleting not just a word but the entire console is astonishing.)

Firefox 112.0.1 on Ubuntu 22.

Regarding the answers to Change key bindings (keyboard shortcuts) in Firefox Quantum:

Errge's "patch firefox" answer fails in Ubuntu 22, because firefox is now in /snap which is a read-only filesystem, thus unpatchable.
Benedikt's answer using autoconfig failed to disable Ctrl+W, with config.js window.document.getElementById('key_close');. I don't know why.
The other answers aren't for Linux.

This might be time to learn a new paradigm - Ctrl [or Cmd] W is universally accepted as 'Close Window'… in just about everything else. — Tetsujin, Apr 30 '23 at 18:55
This was addressed in https://superuser.com/questions/1271147/change-key-bindings-keyboard-shortcuts-in-firefox-quantum . As @Tetsujin, states, however, currently Ctrl-W is used in many applications as the shortcut for closing tabs, -- Brave Browser, Kate, Okular, Notepad++, PDF XChange Editor, etc. — DrMoishe Pippik, Apr 30 '23 at 19:14

@DrMoishePippik But those (non-browser) apps rarely wrap a bash shell, which is the only place I'm tempted to instinctively Ctrl+W. — Camille Goudeseune, Apr 30 '23 at 21:21
