A new third-party extension for Google’s Chrome browser aims to allow users to boycott United Airlines.

The “Drop United” tool blocks United flights from showing up in results for several major travel search engines.

Passengers searching for flights will no longer see United on Google Search, Google Flights, Kayak and Expedia, according to the extension's website, which doesn't say who created the tool.

“Corporations can treat you like s--- because you’ll eventually forget you were ever mad,” the website reads. “Drop United is a Chrome extension that drags United Airlines off your flight search results.

“So the next time you search for a flight, United won’t have a seat in your options. Welcome to the United States of Humanity.”

Mashable first reported on the extension, which comes as a United passenger plans on suing the airline after he was violently dragged off one of its overbooked flights last Sunday.

David Dao’s legal team says the 69-year-old suffered a concussion, broken nose and lost two teeth during the incident.

The Kentucky physician had boarded a United flight from Chicago to Louisville when the crew announced that four seats were needed for accommodating airline personnel.

Dao was among several passengers randomly selected to leave the flight after no volunteers accepted offered compensation. The doctor refused to leave, prompting security officers to drag him down the aisle by his wrists.

The confrontation was captured on video that has since been widely shared on social media, leading to backlash against the company.

United CEO Oscar Munoz has repeatedly apologized for the controversial event, and the business reportedly plans on compensating the full ticket price for all customers aboard Sunday’s flight.
