Short answer: Install only a transparent Chrome extension with a real website, visible permissions, and a clear explanation of what it does. Avoid random scripts or downloads.
- Use the official Chrome Web Store listing.
- Check permissions before installing.
- Confirm it is Canvas-specific, not a generic script.
- Test with non-critical Canvas pages or the tracking test.
- Understand the limit: no extension should claim to change grades or hack school servers.
