but it did not seem to address this issue specifically. 

I have searched, read up, and attempted many tricks to stop "/" from pulling up the quick find menu. However, nothing seems to work for me. On certain websites (with poor interfaces), the "/" key opens up the quick find menu, despite a text field being selected. Is there a workaround to disable it? I tried saka key, as suggested by mozilla support pages (https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly?redirectlocale=en-US&as=u&redirectslug=Keyboard+shortcuts&utm_source=inproduct) but it did not seem to address this issue specifically. I tried entering many variations of the disable searchkeys command in about:config but they didn't work either. Does anyone know a fix?
