This guide focuses on a maintainable approach: use official upstream sources, make one meaningful change at a time, and keep a clear recovery path if a Discord or Moonlight update changes behavior.
Choose by outcome
Pick extensions because they solve a specific workflow problem rather than because a long list looks impressive. Fewer extensions usually means fewer compatibility variables.
Check the source
Prefer extensions from the official repository or from developers you can verify. Read the manifest and permissions or behavior description before enabling unfamiliar code.
Watch compatibility
Discord changes frequently, so an extension that worked last month can temporarily break. Update Moonlight and the extension repository before assuming your local setup is damaged.
Review after updates
When a major client update lands, disable nonessential extensions and re-enable them one by one. This keeps troubleshooting predictable and reduces unnecessary reinstallation.
