Wurdearring: 3 fan de 5 stjerren

Unfortunately auto language switching doesn't work since Thunderbird 8 on Windows and it makes Thunderbird not responding. After a while it is possible to stop the script via the TB dialog. I had to disable the it. Can you please fix this again?

Dizze beoardieling giet oer in eardere ferzje fan de add-on (1.3.2.1-signed.1-signed).
