Ctrl + Shift + C Should Copy 作者: jscher2000

Injects a script into pages to intercept Ctrl+Shift+C as a copy command, not allowing it to open Developer Tools.

Note: only works in web pages, not in the URL bar, internal Firefox pages, etc.

Concerned about permissions? There is no convenient way at the moment to have Firefox run this extension on every site without "all sites" permission. However, you can look at what the script does, it's minimal. https://github.com/jscher2000/Ctrl-Shift-C-Should-Copy/blob/main/content.js

<em>You also can use an online extension reader to extract the files for review. For example:</em> https://robwu.nl/crxviewer/?crx=https%3A%2F%2Faddons.mozilla.org%2Fen-US%2Ffirefox%2Faddon%2Fctrl-shift-c-should-copy%2F

If you use Greasemonkey, Tampermonkey, Violentmonkey, or FireMonkey, you also could consider using the above file in a user script.
