What our analysis found
Otto: Pomodoro timer and Website Blocker, used by 60,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can observe network requests. It comes from a trusted publisher and was last updated in September 2026.
Analyst notes
The extension is a legitimate Pomodoro timer and website blocker. The broad permissions (declarativeNetRequest, scripting, <all_urls>, tabs) are necessary for its stated functionality. The reviewed source code (contentScript2.,, manifest) shows no malicious behavior. The publisher is Google-trusted, the extension is featured, and user reviews are positive. The ML model likely flagged the permission set and generic bundled code patterns, which are normal for this category.
