One image can tell more than a thousand words... Is what this extension is asking for reasonable?
There are (at least?) five actions it is requesting permission that I do not see what it would need for:
- Read all your data on the websites you visit
- Change all your data on the websites you visit
- Manage your apps
- Manage your extensions
- Manage your themes
PS: Viber is an Instant Messaging platform, similar to WhatsApp. This extension allows for using Viber inside Chrome. Otherwise, to use it in a PC one has to install the Viber app.
For the purpose of the text search features, and indexing, the alert says:
Read and change all your data on the websites you visit
Manage your apps, extensions, and themes
