Which browsers does it work in?
Desktop Google Chrome (Chrome Web Store) and Microsoft Edge (Edge Add-ons). Mobile browsers don't support extensions like this.
Why does Chrome say “not trusted by Enhanced Safe Browsing”?
With Enhanced protection on, Chrome shows “Proceed with caution” for extensions from developers it doesn’t know yet. Google says new developers generally take a few months to become trusted. ChatCairn is reviewed and published on the Chrome Web Store and Edge Add-ons, and your chats stay on your device, so it’s safe to choose Continue to install.
