What's New?

• Fixed issue where the addon doesn't work for some people
• Addon will minimize faster (there was 200 ms delay)
• Ensure compatibility with Thunderbird v91

Known Issues:

• Thunderbird icon in tray may disappear if you have the "move to tray when minimized" option enabled in the preferences, this is an issue from TB itself and nothing I am aware of can be done about it.
