Migration Pattern

All Chrome API calls should be replaced following this pattern:

Storage API

// Before
await chrome.storage.local.get(['key'])
await chrome.storage.local.set({ key: value })
await chrome.storage.local.remove(['key'])

// After
await browserAPI.storage.local.get(['key'])
await browserAPI.storage.local.set({ key: value })
await browserAPI.storage.local.remove(['key'])

Tabs API

// Before
chrome.tabs.create({ url })
chrome.tabs.query(queryInfo)

// After
await browserAPI.tabs.create({ url })
await browserAPI.tabs.query(queryInfo)

Runtime API

// Before
chrome.runtime.sendMessage(message)
chrome.runtime.getURL(path)

// After
await browserAPI.runtime.sendMessage(message)
browserAPI.runtime.getURL(path)

Context Menus API

// Before
chrome.contextMenus.create(properties, callback)
chrome.contextMenus.removeAll(callback)

// After
await browserAPI.contextMenus.create(properties, callback)
await browserAPI.contextMenus.removeAll(callback)

Alarms API

// Before
chrome.alarms.create(name, alarmInfo)
chrome.alarms.onAlarm.addListener(callback)

// After
await browserAPI.alarms.create(name, alarmInfo)
browserAPI.alarms.onAlarm.addListener(callback)

Testing Checklist

After completing the migration, test the following:

• Extension loads without errors in Firefox
• Storage operations work correctly (save, load, delete notes)
• Sync functionality works with Supabase
• Context menus appear and function correctly
• Popup opens and displays notes
• Background script handles alarms and messages
• Content script communicates with background script
• Theme settings persist across sessions
• Premium features work correctly
• User engagement prompts display correctly

Notes

• The browser-api.js file must be loaded BEFORE any other scripts that use browser APIs
• Update manifest.json to include browser-api.js in the appropriate script arrays
• Firefox uses browser.* namespace natively, which returns promises
• Chrome uses chrome.* namespace with callbacks, which the wrapper converts to promises
• The wrapper handles both Firefox and Chrome environments automatically
