I tried to remap the Tools > Page Info shortcut from ''Cmd + I'' to ''Ctrl + Opt + Cmd + I '' in macOS keyboard settings, however, despite the keyboard shortcut listed beside Page Info appearing to change, "Cmd + I" still brings up Page Info. I read on another [[https://support.mozilla.org/en-US/questions/1287036]] post that the Shortkeys extension might help but the developer info page states that default keyboard shortcuts cannot be modified with the extension. Creating an autoconfig file was also suggested [[https://support.mozilla.org/bm/questions/1381773] elsewhere, but I don't seem to have a defaults/pref directory in Contents/Resources inside Firefox.app. A guide on what to put in these files to change the default keyboard shortcut for ''Page Info'' would also be appreciated.
