ScriptBlocker: The Ultimate Guide to Blocking Malicious Scripts

ScriptBlocker Installation & Configuration: Step-by-Step Setup Guide

Overview

A concise, practical guide to installing ScriptBlocker and configuring it to block unwanted scripts while minimizing site breakage.

Requirements

• Supported browser (assume Chrome/Chromium-based or Firefox)
• Internet connection
• Basic familiarity with browser extensions

1) Install ScriptBlocker

1. Open your browser’s extension/add-on store:
   • Chrome/Edge: Chrome Web Store
   • Firefox: Firefox Add-ons
2. Search for “ScriptBlocker” and select the extension published by the official developer.
3. Click Add to browser / Install and accept requested permissions.

2) Initial setup

1. After installation the extension icon appears in the toolbar. Click it.
2. Complete any first-run prompts (allowing default protections). Accept the default blocking mode to start safe.

3) Configure global blocking mode

1. Open the extension’s main settings page from the toolbar menu.
2. Choose a global mode:
   • Strict: Block all third-party and inline scripts (maximum protection, higher site breakage).
   • Balanced (recommended): Block known trackers and third-party scripts, allow essential site scripts.
   • Permissive: Allow most scripts, only block known malicious sources.
3. Save the selection.

4) Whitelisting and per-site rules

1. Visit a site that breaks after enabling ScriptBlocker.
2. Click the extension icon → toggle the rule for that site:
   • Allow site: temporarily or permanently permit all scripts.
   • Allow essential: permit inline and first-party scripts only.
   • Block third-party: keep strict blocking for external scripts.
3. Manage site rules centrally in Settings → Site Rules to edit or remove entries.

5) Custom blocklists and allowlists

1. In Settings → Lists, add custom block/allow lists (URL patterns or domains).
2. Import commonly used blocklists (Adblock-format lists) if supported.
3. Set list update frequency (daily/weekly).

6) Script categories and granular controls

1. In Settings → Script Types, enable/disable categories: trackers, analytics, ads, widgets, third-party JS, inline JS.
2. Use the live logger (Settings → Debug/Logger) to identify which script was blocked when a page breaks.
3. Create a rule from a logger entry to allow that specific script/domain.

7) Shortcuts & automation

1. Enable keyboard shortcuts for toggling ScriptBlocker in your browser’s extension shortcut settings.
2. Use “temporary allow” to permit site scripts for the current tab/session only.

8) Advanced settings

1. Configure strict CSP enforcement if available (imposes Content Security Policy rules).
2. Enable automatic updates for the extension and blocklists.
3. Turn on telemetry only if you want to contribute anonymous events (off by default for privacy).

9) Troubleshooting

• Page broken? Use the logger, then temporarily allow the script/domain and add it to the allowlist if necessary.
• Extension not working? Restart browser, ensure extension is enabled, check for conflicting extensions (other script blockers).
• Performance issues? Switch from Strict to Balanced mode or exclude heavy domains.

10) Security maintenance

• Keep the extension and browser up to date.
• Periodically review site rules and blocklists.
• Revoke unnecessary site allows.
