## Description

Content Section Blocker

Content Section Blocker lets you permanently hide anything you don't want to see - ads, banners, promoted posts, sidebars, cookie notices, sticky headers, or any other page clutter.

How It Works
🎯 Pick an Element

Click "Pick an element on the page", then select anything you want to hide. Element Blocker automatically generates a CSS selector and hides it instantly.

📝 Paste a Selector

Already know the selector? Enter any CSS selector (such as .class-name or #element-id) to block the element directly.

🌐 Per-Site or Global Rules

Choose whether a rule applies only to the current website or to every website you visit.

✏ Fully Editable

Enable or disable rules, edit their selectors, or delete them at any time. All rules are stored locally and persist across browser sessions.

⏯ Master Switch

Pause or resume all blocking with a single click from the extension popup.

Fast and Seamless

Rules are injected as a stylesheet as soon as a page begins loading, preventing blocked elements from flashing before they're hidden. Dynamically added elements are also blocked automatically.

Private by Design
No account required
No tracking
No data collection

All rules are stored exclusively in your browser's local storage and never leave your device.
