為什麼最近無法出現可以整理及複製youtube字幕的功能?

La verdad a mi si me ha sido muy útil, hasta para entender mejor cuando hablan rápido en el video, sobre todo en inglés. Siempre hay espacio para mejorar pero es una herramienta muy buena.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Glasp Web Highlighter: PDF & Web Highlight requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
