This might not be relevant for most of the people reading this, but in Japan, we have a very strict content filtering installed in the browser of new 3DSes by default, which makes the Internet browser almost unusable.
To make matters worse, Nintendo stopped supporting credit cards on 18 Jan, which was the only way to remove the filtering.
It means if you haven't removed it by now, you can never access websites like Twitter, YouTube and Amazon on 3DS.
So here is a GodMode9 script capable of disabling the filter. You can't re-enable it from the browser's settings menu, so the script can also enable the filter.

Have fun!
