Wurdearring: 4 fan de 5 stjerren

It's great, but for some reason it stops working every now and then. For the people that can't get it to work at all, try installing it from the add-on page: https://addons.thunderbird.net/nl/thunderbird/addon/expression-search-ng/?src=ss - that seems to make it active.

Dizze beoardieling giet oer in eardere ferzje fan de add-on (3.6.3).
