+### Extensions
-## Extensions:
+We highly recommend the use of [Privacy Redirect](https://github.com/SimonBrazell/privacy-redirect#get),
+a browser extension that automatically redirects Youtube URLs to any Invidious instance and replaces
+embedded youtube videos on other websites with invidious.
-[Extensions](https://docs.invidious.io/Extensions.md) can be found in the wiki, as well as documentation for integrating it into other projects.
+The documentation contains a list of browser extensions that we recommended to use along with Invidious.
