Mr Trump has threatened to shut down the internet if he gets in power but some quick code means that you can shut him out of the internet first.
The software analyses websites for the use of his name and stops access to any website that contains it.
Its creator says that the tool hasn’t just been created to filter out the often incendiary pronouncements of the presidential candidate but in the hope of broadening the debate, too.
“I hope folks will take this opportunity to learn more about the wide field of candidates out there,” Rob Spectre, who created the Trump Filter, told CNN. The extension could allow people to actually learn about the issues that are at stake in the race to be the Republican candidate for president, he said.
The filter comes with three degrees of force mild, aggressive, and vindictive. The former shuts down access to Trump’s own Twitter, while the latter entirely bans news websites that write about him.
Donald Trump has previously said that if he was in power he would look to shut down the internet or at least parts of it. He has said that he is worried the web is being used to recruit extremists, and that as a result various parts of it should be turned off.
