Browser extensions are unofficial tools made to improve the Duolingo learning experience.
(Remember to exercise caution before installing these extensions)
⚠️ Notes:
- These extensions could stop working at any time (or negatively affect duolingo features) if Duolingo changes its functionality.
- Open-source extensions tend to be safer (This does not mean Closed-source extensions are dangerous).
- If an extension is on an addon/extension store (Ex: Chrome webstore) they are generally safe.
- Extensions are labeled inactive if they haven't been updated after 2 years.
