Firefox - Get "Highlight all" button to be on by default
Starting at Firefox 50 you can change the default value in the settings.
- Type
about:config
in the browser's address bar and hit enter. - Confirm you will be careful if the warning prompt appears.
- The parameter
findbar.highlightAll
determines whether highlight all is enabled or not when you search in Firefox.

You could try the latest version 1.3.4 of FindBar Tweak. https://addons.mozilla.org/en-US/firefox/addon/findbar-tweak/versions/
The "Highlight All" checkbox can be found in the extension's "Highlight" preferences panel.
You don't need any extension nor to go to about:config.
Since Firefox 54, just do a search (ctrl
+f
) and enable highlight all (alt
+a
). It will remember that automatically on future searches.
It is not necessary anymore to enable it through about:config
