Is Theme & Color Changer for YouTube - Colorize YouTube safe?

Low risk

Theme & Color Changer for YouTube opens promotional tabs on install and every update without user interaction.

On installation, the extension automatically opens a tab to addonup.com requesting a review. On every background update it opens a second promotional tab to the same domain. Both actions fire silently with no user prompt or consent.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Shared hosts - 1 hostname

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.
