Uninstalling Stationary

Q: How do I uninstall the stationary in Thunderbird. It has never worked and now today there was an update, which left this,

A: -I'm sorry for publishing new version of my extension with this error. It has been caused by little malformed English translation file (*.dtd). Simply my native is Polish, and i commonly use pl-PL locale for work and testing. Anyway, i already published fixed version (0.4.6.1). -Goto Tools>Add-ons>Extension . If you select 'stationary' in list , an uninstall button will be visible on it . Click on it . Now restart Thunderbird .
