about:blank tabs clutter the browser when opened by websites as popups or intermediary pages. This extension automatically cleans them up, reducing tab clutter and improving browser tidiness.

Extension runs in the background (service worker). When a tab is activated or updated, it checks if the URL is 'about:blank'. If so, it starts a 5-second timer. After 5 seconds, it re-checks the tab URL. If still about:blank, it removes and discards the tab. If the tab navigated elsewhere, it does nothing.

Target users: Users who encounter many about:blank popup tabs from websites / Users who want automated browser tab cleanup / General productivity-focused browser users

Extension is very small (36 lines of JS) so the analysis covers the entire codebase — no hidden complexity.
No UI/popup/options page exists, so there are no additional files to inspect for paid or login features.

Monetization

No paid features detected

No payment code, no subscription logic, no premium gating, no upgrade prompts. The only keyword hit ('pro') was inside _metadata/verified_contents.json which is Chrome's standard signature metadata file, not actual paid feature code.

Confidence: 100
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension has no login UI, no account system, no authentication flow, and no network requests to any external service. It only uses the local chrome.tabs API to monitor and close tabs.
