About this Add-on
Undo Send Delay is a lightweight Thunderbird add-on designed to give you a crucial grace window after hitting send.
Have you ever pressed Send or hit Ctrl + Enter a second too early, only to immediately realize you forgot an attachment, left out a key recipient or worse select the wrong recipient?
This add-on gives you those extra couple of seconds to change your mind.
Key Features:
Customizable Delay: Adds a short delay before your email is actually dispatched. Defaults to 5 seconds, but you can easily adjust the duration in the settings menu to fit your workflow.
Visual Countdown: Spawns a clean, modern dark-mode popup featuring a smooth, synced countdown timer and visual progress ring.
One-Click Cancel: Provides a prominent Undo Send button to instantly abort transmission and keep your email in the compose window.
Fail-Safe Protection: Automatically cancels sending if the delay window is closed manually, ensuring you never accidentally dispatch an email while managing the prompt.
Lightweight & Seamless: Integrates natively into Thunderbird's composition process using standard WebExtensions APIs for minimum overhead.
