Is Stylus (beta) safe?

Stylus (beta) applies user-authored CSS styles to websites and includes hardcoded OAuth client secrets for optional cloud sync providers.

Stylus (beta) is an open-source browser extension that injects custom CSS into web pages at the user's direction, allowing visual customization of any site. It supports optional style synchronization via Google Drive, OneDrive, Dropbox, or UserStylesWorld using bundled OAuth credentials. The OAuth client secrets for these providers are embedded directly in the extension bundle rather than fetched at runtime.
