On this page, you'll find a list of the add-ons I have been developing since 2010. I have also included those that are no longer compatible with the newer versions of Thunderbird for historical reference. Add-ons are meant to enhance your Thunderbird experience. Customize your email client, improve productivity, and add new features.
Enjoy!

Active addons

• MS 365 Link Opener Open shared SharePoint and OneDrive links directly in the Word, Excel or PowerPoint desktop app, instead of the browser.

• ThunderAI Use ChatGPT, Gemini, Claude or Ollama with your custom prompts to analyse, write, correct and tag your emails.
• ThunderJira Create Jira issues from any email and turn issue links into clickable badges. Works with Jira Cloud and Server / Data Center.
