This question was already asked [[https://support.mozilla.org/gl/questions/1241294|in this thread]] but the solution doesn't work for me. In '''about:config''', no matter what value I give to '''permissions.default.shortcuts''', sites are still able to intercept my keyboard shortcuts (eg Ctrl+f). I can disable it for ''individual ''sites, using''' Page Info > Permissions''', but I'd like this turned off across the board because I find it creepy when sites mess with my controls.
