Google's Chrome holds a 65% market share and faces potential break-up actions from the Department of Justice. Microsoft is promoting its Edge browser to Windows users, highlighting enhanced security features through Microsoft Defender SmartScreen. Microsoft encourages enterprises to adopt Edge, suggesting that employees may also use it at home, threatening Chrome's user base. In response, Google has launched a campaign to reassure its 3 billion Chrome users about its security measures, emphasizing its innovations and commitment to user safety. Google is also addressing privacy concerns related to tracking cookies and plans to introduce an opt-in tracking mechanism, while Microsoft is developing the “Privacy-Preserving Ads API” for Edge. Both companies are focusing on security and privacy as key competitive factors. Chrome has recently updated to version 130.0.6723.58/.59, and users are advised to restart their browsers after the update for optimal security.
