How do I disable keyboard shortcuts?

Some of the sites I visit allow me to format text with control characters (eg ctrl-b to bold the text). However, Firefox interrupts the control characters and opens the bookmark sidebar instead. How can I override this shortcut (and, perhaps, almost every shortcut)? Thank you, Ben

What sites and screenshot of the error so others can test what your saying.

It happens on any contenteditable element.

For example: MDN Contenteditable

Select some text in the editor on that page and try to bold it using cmd+b OR ctrl+b and it will open the bookmarks sidebar.

I just want to be able to disable or turn off that shortcut, so those content editors work correctly.

Firefox 65 changed how key events on non-printing keys are sent to websites. Previously, a site would get a "keydown" and a "keypress", but starting in Firefox 65, it only got a "keydown".

CTRL+i also opens bookmarks toolbar (instead of making text italic). I tried installing Shortkeys (addon) and disabled CTRL+b and CTRL+i, but it doesn't work, firefox still intercepts the keypress and opens the effing bookmarks bar.

This happens to me on Mac with Command–[comma] on Google Drive, which should insert a subscript in the document, but instead is intercepted by Firefox which opens my Preferences.

Infuriatingly, there does not appear to be any way in the Preferences tab which I keep opening to disable keystrokes, and on top of that, this command isn't even listed in any of the lists I can find of keyboard shortcuts for Firefox in the first place (e.g. https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly).
