exwm-firefox-evil makes firefox’s control scheme modal. It uses vi-like keys and doesn’t require any addons. It does this by implementing exwm-firefox-core which sends fake keys to firefox using exwm.
To get link-hints you have to download a link-hint addon to firefox and define a new function to send that key to firefox on call like those in exwm-firefox-core.
(require 'exwm-firefox-evil)
;; Auto enable exwm-firefox-evil-mode on all firefox buffers
(add-hook 'exwm-manage-finish-hook 'exwm-firefox-evil-activate-if-firefox)You also need to add escape to exwm-input-prefix-keys so that escape is passed to emacs instead of firefox.
(dolist (k `(
escape
))
(cl-pushnew k exwm-input-prefix-keys))Keep in mind that this affects all exwm-applications. If you want to get your escape key back in those applications you could bind the escape key to (exwm-input--fake-key 'escape) in your own minor mode that activates in all exwm-buffers just like I did in this package. For the conditional statement to avoid firefox buffers, just negate the checks in the function exwm-firefox-evil-activate-if-firefox
