What our analysis found

Horizon HTML5 Redirection Extension, used by 200,000 people, showed no malicious code in Extension Auditor's review. It comes from a publisher with 7 extensions and was last updated in July 2026.

Analyst notes

The extension is a legitimate enterprise tool (Horizon HTML5 Redirection by Omnissa) that redirects HTML5 media from virtual desktops to the client. All network communication is to localhost (native messaging and local WebSocket). Permissions are broad but necessary for intercepting video elements on any page. No data exfiltration, tracking, or external network requests. The ML and risk-engine flags are based on broad permissions and code patterns typical for its functionality, not malicious behavior. Publisher is reputable with no malicious history.
