The Justice Department wants the search giant to divest the Chrome web browser, among other provisions designed to limit its market power.

Google's parent company saw its stock fall Thursday after the Justice Department indicated it could try to force a sale of Google's Chrome web browser.

Shares of Alphabet lost more than 5 percent Thursday morning. In a court filing late Wednesday, the Justice Department said Google "must promptly and fully divest Chrome" to a buyer approved by the plaintiffs in an antitrust case. It was one of multiple remedies proposed by regulators, following a federal judge's August ruling that Google has an illegal monopoly on internet searches.
