if this add on is useful... its not very intuitive. spent about 10 mins trying to figure out how it works... to no avail.

When I load dictionary, the definitions appear in some Asian language. I want definitions in English, not Chinese or Japanese. Rest of the extension works well, though, and is very fast.

Only works with an Asian language. Cannot reset or download additional dictionary despite the help file pointing to options that don't exist.

Nightly (2019-07-15) - Options page has only option to load dictionary. I can not manage uploaded dictionary and there is no options section so I can not for example set "Lookup both capitalized and non-capitalized headers" and that's why I can not use Webster dictionary.
Anyway thanks for Your work.
