|Launch date||December 2010|
CWS was publicly unveiled in December 2010, and was opened on February 11, 2011, with the release of Google Chrome 9.0. A year later it was redesigned to "catalyze a big increase in traffic, across downloads, users, and total number of apps". As of June 2012, there were 750 million total installs of content hosted on CWS.
Some extension developers have sold their extensions to third-parties who then incorporated adware. In 2014, Google removed two such extensions from CWS after many users complained about unwanted pop-up ads. The following year, Google acknowledged that about five percent of visits to its own websites had been altered by extensions with adware.
Malware remains a problem on CWS. In January 2018, security researchers found four malicious extensions with more than 500,000 combined downloads. In February 2021 Google blocked "The Great Suspender" a popular extension with 2,000,000 users after it was reported that malicious code was added to it.
