Very good and more stable than Tamperamonkey/Violentmonkey. It also works with Edge canary on Android, but unfortunately the icons such as “run on startup” are hidden in the browser bar.
Does one thing and does it right. This is the code injection extension you're looking for.
超级好用！！！
Amazing Extension
Very good extension, respect!
weird how when i save it jumbles up all my code :(
特徴は他の人が書いている通りシンプルで使いやすく素晴らしい。全く知識がなくても、Copilotに質問して生成したコードをほぼべた張りするだけで思った通りの機能を実現できた。 欠点は寄付したくなってもよく分からないサイトに登録するか、またはビットコイン送金しか手段が無いこと。Paypalとかあれば良かったのだがちょっとハードルが高い。
Superb. Works really well, and a great UI.
Look very good with nice clean interface!
Great extension, I love that I can find the same features and shortcuts as in VS Code, it's really a great experience ^^
