This extension is malware. Do not install. It modifies user's web requests and tracks them across all sites. It has layers of obfuscation to hide this malicious behaviour. I have read the source code, this is not a baseless assumption.

Uso o WhatsApp Web com frequência, e esta extensão ajuda a manter minhas conversas mais privadas quando outras pessoas estão por perto.

Nice little extension for privacy. I use WhatsApp Web at work sometimes, and this makes it easy to blur chats quickly when people walk by. Simple and works well.

Bravo

Très bonne extension, pour contrer les regards irrespectueux !

Boa noite.
Continuemos.
Grato.

Ok

Does exactly what I need. Working from public space feels much more comfortable.
