Is SEO Extension ROSSK Free SEO Checker, Link Analyzer, SEO Toolbar,Site Audit safe?

Low risk

SEO Extension ROSSK writes user-agent spoofing settings into each visited site's localStorage.

When user-agent spoofing is configured, the extension stores the selected user agent, vendor, and platform in localStorage on pages it visits, then injects a script that reads those values to modify navigator fields. Its Web Vitals feature also sends the current tab URL or origin to Google's Chrome UX Report API when the user runs that check.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.
