User Reviews

Blurs as expected. TY!

Fairly simple to use. Really good extension if you're like me and love horror content but are very easily spooked by faces in the thumbnail. There's similar extensions, but if you just wanna blur thumbnails out all together then this does the job!

Is Blurred thumbnails 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.

Blurred thumbnails requires a few sensitive permissions. Exercise caution before installing.
