Quote:Mozilla plans to integrate a keyboard shortcut manager on the about:addons page of the Firefox web browser.

Firefox extensions may map keyboard shortcuts to certain functionality; keyboard shortcuts may speed up certain operations as it may be faster to use them instead of navigating through mouse or touch-based menus.

Firefox 66, currently available as a Nightly development version, features the new functionality already.

Firefox users who open about:addons in Firefox 66 may notice a new "keyboard shortcuts" link on the manage your extensions page.

A click on the new button opens a new page that lists all keyboard shortcuts mapped by all extensions that are enabled in the web browser, and keyboard shortcuts that may be mapped.
