- Saves time by allowing direct downloads without manual copying or pasting.
- Compatible with various websites for downloading media.
Cons

- Limited functionality compared to expected features like direct MP3 downloads.

All I get is a very narrow sidebar that doesn't do anything and a black screen. No download media from link or no cobalt extensions. I would give it 0 stars if I could.

Is cobalt downloader Safe?
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.
