Overview

Product summary

Review the store description, core capabilities, and common use cases.

This extension is for anyone, who uses websites with pop-up ads (ads that open in a new tab).

red icon -> TabBlock prevents opening any new tab.

green icon -> TabBlock allows opening new tabs freely.

Note! Redirections to ads in the same tab still work! You can try to block them by using other extensions or simply return with "back" button.

TabBlock does not block any normal ads.

Manifest v3 Update: The new approach in Manifest v3 prevents extensions from running in the background all the time, leading to a cold start that can significantly increase the time needed to close a new tab. However, this is purely a cosmetic downgrade - TabBlock now filters out all requests to new tabs instantly, in addition to its ability to close tabs.

AI product read

Block unwanted new tabs (pop-up tabs) by automatically closing them or preventing them from loading.

Prevents annoying pop-up ads that open in new browser tabs on certain websites, giving users a cleaner browsing experience.

User clicks the extension icon to toggle blocking on (red icon) or off (green icon). When on, any new tab creation is either immediately closed (via tabs.onCreated listener) or blocked at the network level (via declarativeNetRequest rules that block main_frame requests for non-existing tabs). Existing tabs remain unaffected.

Target users: Users who visit websites with pop-up tab ads / General web users who want to control new tab creation

Extension is very small (6 text files, ~41 lines of core logic), so the analysis is comprehensive and deterministic.
No external network requests beyond the standard Chrome Web Store update URL.

Monetization

No paid features detected

No payment logic, subscription, premium features, or upgrade flows exist in the source code. The 'pro' keyword hit is a false positive from base64-encoded content in _metadata/verified_contents.json (Chrome's verification metadata). All features are available immediately with no gating.

Confidence: 100
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension requires no login or account. All state is stored locally using chrome.storage.session (browser session storage). No external APIs, authentication flows, or user accounts are involved. The 'session' keyword hits are false positives referring to Chrome's session storage API, not user login sessions.
