I find the Quick Find keyboard shortcut
' for links in Firefox very useful for navigating a large portion of the web with keyboard only, but I notice that it doesn't work with most overlaid content, for example most GDPR dialogs or prompts to please log in or register. Is there a setting or add-on for Firefox to fix that or would a simple change to the HTML make that content searchable with Quick Find?
Example: Delete cookies. Open Yahoo. Press
'OK. Search result not found. Press
Ctrl-F OK. Search result found. Then it's possible to press
Shift-Tab to select the
OK link, but by pressing the apostrophe key it apparently never works for any links on overlay windows.
