Wurdearring: 5 fan de 5 stjerren

Is it because this is still in EXPERIMENTAL status that it is not being updated automatically in Thunderbird?

Dizze beoardieling giet oer in eardere ferzje fan de add-on (0.4.7).  Dizze brûker hat oare beoardielingen fan dizze add-on.

The Add-ons in the sandbox(EXPERIMENTAL) is not being updated automatically.
I will nominate this add-on for become public with next version.

Best Regards,
