Thank you. Your add-on has enabled me to continue using my Stardock Windows interface skin with the *latest* version of Thunderbird. Before I discovered Titlebar Tabs Cleaner, I was stuck using Thunderbird 16, since all newer versions of Thunderbird wreaked havoc with my Stardock interface skin. Awesome.
... I use Windowblinds also! There seems to be an arms race between Mozilla and the OS skinners to obliterate each other. I am usually doing my best to keep the Mozilla site in check (I know it looks great with Windows Aero, but not every Windows user has Aero)
