Hi Guixers,

In Icecat I can download add-ons in this website:

https://addons.mozilla.org/en-US/firefox/collections/11536848/webextensions/

e.g. Duden-Mentor-Textprüfung
Oxford Advanced Learners Dictionary
Cambridge Dictionary
ImTranslator: Translator, Dictionary, TTS
Language Switch

In Chromium I can download add-ons from the chrome web store:

https://chrome.google.com/webstore/category/extensions
e.g. Wayback Machine

How can I check if an add-on is proprietary software?


Kind regards

Gottfried
