Allow opening a new tab with Ctrl+T on all websites in Firefox
- by Martin J.H.
In Firefox, certain websites and plugins (Adobe PDF Plugin) appear to "capture" the Control key, so that when I try to open a new tab using "Ctrl+t", nothing happens - or worse, something unexpected happens.
Examples:
On the Codecademy site, while editing code, Ctrl+T either does nothing, or (when Flash is disabled) switches the position of the two characters next to the cursor.
When viewing PDF's with the Adobe PDF Plugin, Ctrl+T does nothing.
Is there a way to disable this "feature"? I would like "Ctrl+t" to always "talk" to Firefox!
Edit:
After searching superuser deeper, this question is very similar to the questions:
"How to prevent keystroke grabbing/hijacking by websites in Firefox?"
"How do I prevent pages I visit from overriding selected Firefox shortcut keys?".
The answers to these questions are interesting and relevant, but do not give a method on how to disable combinatinos such as "Ctrl+t". Maybe a modified Greasemonkey script is the easiest solultion.
Edit 2 - Attempt at a solution
The following UserScript (Use GreaseMonkey to install it) successfully captures Ctrl+t on some sites (Google Search site, for instance - PopUp "Gotcha" appears), but not on the Codecademy site. I found another question pertaining to this subject here: "How to forbid keyboard shortcut stealing by websites in Firefox". It was raised in 2010, and the consensus was: It can't be done.
// ==UserScript==
// @name Disable Ctrl T interceptions
// @description Stop websites from highjacking keyboard shortcuts
//
// @run-at document-start
// @include *
// @grant none
// ==/UserScript==
// Keycode for 't'. Add more to disable other ctrl+X interceptions
keycodes = [84];
var lastPressedButton = [0];
document.addEventListener('keydown', function(e) {
//uncomment to find out the keycode for any given key
// alert(e.keyCode );
if (keycodes.indexOf(e.keyCode) != -1 && e.ctrlKey) {
e.cancelBubble = true;
e.stopImmediatePropagation();
alert("Gotcha!");
}
return false;
});
