Works and works well, my only peeve is that it uses Google translate, and so some words are not properly translated. I'm not sure of a better database since I don't read/write/speak Mandarin/Cantonese, but I do know from experience Google translate has a hard time with languages that use kanji.

Great addon, but permissions should look like this:

"permissions": [
"*://*.bilibili.com/*",
"storage"
],

"activeTab" makes browser have lingering dot over every site

Translates the subtitles into english so I can practice Chinese. God tier addon
