User reviews

The add-on successfully downloads YouTube videos quickly and reliably, earning praise for simplicity and effectiveness. However, many users report intrusive ads, virus warnings, and redirects to other sites. The lack of an integrated download button forces users to copy-paste URLs manually, reducing convenience. Despite these drawbacks, some consider it the best available downloader, especially after trying multiple alternatives.

Pros

No visible download button on the video page, requiring manual link copy-paste.
Unwanted redirects leading to unsafe or unrelated content.

Every time click download will load ads and some ads are virus. Starting can download, after that can't download anymore and keep loading virus + ads.

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.

YouTube Downloader requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
