## Description

Flash Inbox is the fastest disposable email add-on on Firefox.

📬 Instant Inbox: A disposable email address is generated the moment you install. Incoming emails appear almost immediately inside the popup, no refreshing needed. The email content is opened directly within the popup, no new tabs.

⚡ One-Click Email Autofill: Flash Inbox detects email input fields across the web and adds a discreet fill button directly inside them. Click it, and your disposable address is inserted instantly, no copying, no pasting, no switching tabs.

🧪 OTP Lab: Uses AI to read incoming emails, extract OTP codes or verification links, and act on them automatically. Codes are copied to your clipboard and auto-filled into the page; links are opened for you. No logs are kept.

🔒 Vault: Need to keep a received email beyond the session? Save it to your Vault with one click. Vault emails persist across sessions and never expire, all stored entirely on your device.

📋 Activity Logs: A clean timeline of every major event. You'll always know what happened and when.

✨ Highlights:

-Automatic address renewal when your inbox expires
-Quota meter to track your usage at a glance
-All your data remains private and stays on your local device.
