How to disable all keyboard shortcuts in Firefox?

Question

Mozilla Firefox

When typing quickly in a Firefox tab, from time to time I accidentally press some key combination on the left side of the keyboard, after which various events can occur with the same result - the typed text is lost.

Since I do not use keyboard shortcuts in Firefox, the question arose - how to disable all keyboard shortcuts in general in this browser (and only in this browser)
After searching through the settings, I could not find a similar function (we are all imperfect :)
