Content Section Blocker Firefox

Content Section Blocker

Force-hide any element on any website. Click to pick an element, or paste a CSS selector like .ad-container or #promoted-post. Rules are editable, toggleable, and stored locally, per-site or globally. No accounts, no tracking, no data collection

Features & Capabilities

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.

Is Content Section Blocker Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Content Section Blocker requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Content Section Blocker is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
