Disabling the proton UI solved the issue for me.

Added the following to the user.js:

user_pref("browser.proton.contextmenus.enabled", false);
user_pref("browser.proton.doorhangers.enabled", false);
user_pref("browser.proton.enabled", false);
user_pref("browser.proton.modals.enabled", false);
user_pref("browser.proton.places-tooltip.enabled", false);
