# Firefox Compatibility Changes

This Firefox version was created from the Chrome extension in `ozhovnuvatyi/sony-pde-token-chrome-ext/`

## Changes Made

### 1. manifest.json
- **Added** `browser_specific_settings` with gecko ID and minimum Firefox version (109.0)
- **Changed** extension name to "Sony PDE Helper (Firefox)" to distinguish from Chrome version
- **Changed** background script from `service_worker` to `scripts` array (Firefox MV3 requirement)
- **Added** `type: "module"` for ES module support in background scripts

### 2. constants.js
- **Changed** from standard constant declaration to ES module export
- **Removed** CommonJS module.exports fallback
- Now uses `export const CONSTANTS = {...}`

### 3. background.js
- **Changed** from `importScripts('constants.js')` to `import { CONSTANTS } from './constants.js'`
- Uses ES6 module syntax (required for Firefox MV3)

### 4. README.md
- Updated with Firefox-specific installation instructions
- Added notes about temporary vs permanent installation
- Added Firefox compatibility information
