CRX Local Installation Guide

📋 When to Use

CRX local installation is suitable for:

• Enterprise intranet deployment
• Development and testing purposes

💡 We recommend using Chrome Web Store installation for automatic updates support.

Click the button below to download the latest CRX package:

Extract Files

1. After downloading, locate the full-page-screenshot.zip file
2. Right-click the file and select Extract All or Extract Here
3. After extraction, you'll get the full-page-screenshot.crx file (or a folder containing extension files)

⚠️ Note: The downloaded file is in zip format. You need to extract it first to see the crx file.

💡 After enabling Developer mode, additional buttons will appear: "Load unpacked", "Pack extension", etc.

📦 Step 3: Install Extension

1. Open File Explorer and locate the extracted .crx file
2. Drag and drop the .crx file directly onto the Chrome extensions page

⚠️ Note: When using this method, do not delete or move the extracted folder, otherwise the extension will stop working.

💡 If none of the above methods work, please see the ZIP installation method below.

📦 ZIP Installation Method

If CRX installation fails, you can use the ZIP method:

Extract the ZIP file to a permanent location (e.g., D:\Extensions\full-page-screenshot)

Step 3: Load Extension

1. Open chrome://extensions/
2. Enable "Developer mode"
3. Click "Load unpacked"
4. Select the extracted folder

Step 4: Complete Installation

The extension is ready to use once loaded successfully

⚠️ Important: After installing via ZIP method, do not delete or move the extracted folder, or the extension will stop working.

🔄 Updating the Extension

Locally installed extensions don't update automatically. To update manually:

1. Download the latest CRX/ZIP package
2. Remove the old version from the extensions page
3. Follow the steps above to install the new version

💡 We recommend periodically checking the official website for new releases.
