LSP Rewrap
LSP Rewrap cleans up plain-text emails by collapsing extra spaces, tabs, and other spacing issues—like older Thunderbird versions did. Use the toolbar button, Ctrl+Shift+R, or Tools → LSP-Rewrap while composing a plain-text message.
Sales force weblink
Add-on for Thunderbird to open Sales force website in a Tab.
Retrieve Remote Avatar
This experimental addon for Thunderbird fetches a remote avatar from various sources if one isn't already set.
By default this addon pulls from libravatar. Custom providers can also be set.
Sum it up
The extension adds a button called Sum it up which takes content of a message and asks a locally running large model to summarize it in 50-100 words. It requires API of a llama.cpp or ramalama server running locally. No content leaves the local host.
ChartPop
Stop opening new tabs! Instantly see stock prices and mini charts by hovering over tickers on any webpage.
Strikethrough Button
Adds a strikethrough toggle button to the Thunderbird compose toolbar. As this is an extension, it is not an integrated component of the Thunderbird toolbar. That is why it sits at the far right on the toolbar and not next to the B/I/U buttons.
SmartQuotes
Applies the correct smart quotes („ ... “ instead of " ... ") used in Lithuanian, German, Czech, and other Central European languages. One click fixes your entire text.
