User Reviews

PERFECT! Exactly what I needed. Now I can watch my favorite videos in huge resolution, with the reassurance that the close window button is always visible in the top-right corner for a quick exit if needed.

The extension works really well. I want to thank the developer. It’s a unique extension with no equal. The only missing feature is the lack of an option to automatically detect videos and maximize them.

Is Universal Video Maximizer 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.

Universal Video Maximizer does not require any sensitive permissions.
