Unable to disable/modify default Quick Find keybindings (the apostrophe key and the forward slash key).
Attempted (and Failed) Solutions:
(1) Not able to use Murphy's solution (https://support.mozilla.org/en-US/questions/1215667), because there is no 'Options' subheading in my 3-bar drop-down menu and I am otherwise unable to find a 'Browsing' subheading.
(2) Not able to use cor-el's solution (https://support.mozilla.org/en-US/questions/984845), because the modification suggested is no longer supported by my version of Firefox (61.0.1 (64-bit) on Linux Xenial).
(3) Not able to use suggestion at https://techdows.com/2018/06/disable-quick-find-firefox.html, because ‘accessibility.typeaheadfind.manual‘ preference is not listed. Toggling value of 'accessibility.typeaheadfind', 'accessibility.typeaheadfind.flashBar', and 'accessibility.typeaheadfind.linksonly' did not disable Quick Find after restarting Firefox.
(4) I also tried adding the preference 'searchkeys.disable.all' to 'about:config' and setting its boolean value to 'true' (I am unable to recall source of this suggestion), but it also did not work.
Your help is greatly appreciated! Thank you in advance for your time and effort!
