I've used this add-on for a long time and it works great on both Linux and Windows. I like keeping Thunderbird open in the background but I hate having it clutter my taskbar.

Those with issues on Ubuntu. This is not an issue with the plugin itself. The Unity desktop (Ubuntu's custom desktop) doesn't use the traditional "Tray" that other Linux OSes use and so the plugin can't put an icon in Unity's tray even though it keeps running in the background.
