About this extension
🎉 Confetti Extension for Firefox/Zen Browser

A simple Firefox extension that triggers a beautiful confetti animation when you press Alt+Z.

🚀 Installation

Method 1: Load as Temporary Extension (Easiest - No XPI needed)
  1. Open Zen Browser or Firefox
  2. Type about:debugging in the address bar and press Enter
  3. Click "This Firefox" (or "This Zen Browser")
  4. Click "Load Temporary Add-on..."
  5. Navigate to the confetti-extension folder
  6. Select the manifest.json file
  7. Done! ✅

Method 2: Install from XPI file

First, create the XPI file:

Option A: Using Python (Recommended)

cd /Users/shimantorehman/Downloads/confetti-extension
python3 build-xpi.py


Option B: Using Terminal

cd /Users/shimantorehman/Downloads/confetti-extension
chmod +x build-xpi.sh
./build-xpi.sh


Option C: Manually create XPI
  1. Select these files:
    manifest.json
    content.js
    canvas-confetti.min.js
    icon.png
  2. Right-click → Compress (creates a .zip file)
  3. Rename the .zip file to .xpi

Then install the XPI:
  1. Open Zen Browser
  2. Go to about:addons
  3. Click the gear icon ⚙️ (top right)
  4. Select "Install Add-on From File..."
  5. Choose confetti-extension.xpi
  6. Confirm installation

⚠️ Note: In Zen/Firefox, unsigned XPI files still install as temporary extensions!

Method 3: Permanent Installation (Requires Signing)

For permanent installation, the extension needs to be signed by Mozilla:
  1. Create the XPI file (see Method 2)
  2. Go to Firefox Add-ons Developer Hub
  3. Create an account and submit the XPI file

⚠️ Note

As a temporary extension, it will be removed when you close the browser. You'll need to reload it each time you open Zen Browser, unless you:
  1. Sign and publish it on Firefox Add-ons (permanent)
  2. Use Firefox Developer Edition or Nightly with disabled signature checks

🐛 Troubleshooting

Confetti doesn't trigger:

Check the browser console (F12) for errors
Make sure you pressed Alt+Z (not Cmd or Ctrl)
Reload the extension from about:debugging

Extension disappears after restart:

This is normal for temporary extensions
Reload it from about:debugging → Load Temporary Add-on

📜 License

Free to use and modify!

Enjoy your confetti! 🎊
