Prioritize Japanese for Han unification (Can be edited to prioritize other langs)
当前为
It is exactly similar to https://greasyfork.org/en/scripts/439780-wanikani-community-prioritize-japanese-glyphs but add more websites.
This script may also be edited to prioritize other langs, like "zh-TW" or "ko-KR", if you really need it.
The script is based on lang attribute, and no CSS is really being injected. (I might add CSS injection, based on common fonts, later.)
This partially related to an Arch Linux issue on Firefox.
