Thunderbird Conversations
Featured
This addon provides a conversation view for Thunderbird, grouping messages together and allowing you to reply "inline" thus providing a more efficient workflow.
KeepRunning
Once you close Thunderbird you will no longer be able to see your new emails. This plugin keeps Thunderbird active in the background, meaning you can still receive your new emails after closing the app. Use this when the app is in the startup.
Blinking Alert
Requires Restart
Adds blink feature to the new-mail alert.
You can also disable auto-hiding of the alert.
TbSync
TbSync is a central user interface to manage cloud accounts and synchronize their contact, task and calendar information with Thunderbird.
Copy Sent to Current
Allows to place a copy of sent messages (aka FCC) into the currently active folder or any other folder you choose, when you create the message. Usually the copies are placed into the 'Sent' folder. For replies, you may also move the original message.
Quick Folder Move
When filing messages, a search box will show up allowing you to quickly enter the folder name you want to move to.
If no search term is entered, a list of recent folders will show up instead.
