Is Qui-Quo safe?
Qui-Quo fetches server-selected content scripts and hot-patch code that can run on any site.
Qui-Quo periodically downloads a content-script manifest from extension.qui-quo.ru and injects the listed scripts into matching tabs with all-URLs access. The same manifest can name bug-fix JavaScript that the extension fetches and executes at document start in those pages. This lets the server change what code runs in pages and what page data that code can read, including URLs, page content, and form fields.
Part of this rating comes from analysis signals we haven't published as detailed findings yet.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 30 hostnames
Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

What it can do
Permissions this extension asks for, as declared in version 2.2.3. Asking for a permission is not a finding on its own - it is what the extension can do if it chooses to.

Where it sends data
Destinations our analysis observed Qui-Quo contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
- extension.qui-quo.ru
Qui-Quo sends data to extension.qui-quo.ru. No other extension we have analysed sends data here.
