Content Zapper

Precision element removal for Firefox. Hover to highlight any page element, click to zap it gone. Your rules persist across refreshes.

How It Works

Click the toolbar icon or press Alt+Z to activate Zapper mode. A red dashed border follows your cursor, hover over any element to preview it, then click to remove it. Press Esc to exit. Made a mistake? Alt+Shift+Z undoes the last zap.

Key Features

• Persistent Zap Rules - zapped elements stay gone on every page load, even after closing and reopening your browser
• Smart Selector Engine - handles sites like Google and GitHub that auto-generate random element IDs, so your rules survive page refreshes
• Selector Blacklist - set CSS selectors in Advanced Settings to auto-zap elements (cookie banners, ad containers) on every page without lifting a finger
• Dashboard - review all your persistent rules and zap history per site, enable/disable individual rules, export your data
• Theme Aware - follows your system dark/light preference, or override it manually
• Undo Support - one-click undo with the on-screen badge or keyboard shortcut
• Zero Tracking - this extension collects no data and transmits nothing outside your browser

Permissions Explained

• \<all_urls> - required to inject the zapper overlay and remove elements on any website you visit
• activeTab - gets tab info when you activate the zapper
• storage - saves your zap rules, blacklist, and preferences locally on your device
• contextMenus - adds a right-click menu option to toggle Zapper mode
• scripting — communicates with content scripts

All data stays on your device. No servers, no analytics, no tracking.
