-FreeTube is supported by the [Privacy Redirect](https://github.com/SimonBrazell/privacy-redirect) and [LibRedirect](https://github.com/libredirect/libredirect) extensions, which will allow you to open YouTube links into FreeTube. You must enable the option within the advanced settings of the extension for it to work.
+You can use the following extensions to open YouTube links directly in FreeTube:
 
-- Download Privacy Redirect for [Firefox](https://addons.mozilla.org/en-US/firefox/addon/privacy-redirect/) or [Google Chrome](https://chrome.google.com/webstore/detail/privacy-redirect/pmcmeagblkinmogikoikkdjiligflglb).
+- LibRedirect
+- RedirectTube
 
-- Download LibRedirect for [Firefox](https://addons.mozilla.org/firefox/addon/libredirect/) or [Google Chrome](https://libredirect.github.io/download_chromium.html).
+[LibRedirect](https://libredirect.github.io/) automatically redirect YouTube links to FreeTube. To make it work, you’ll need to enable the relevant option in the advanced settings of each extension.
+
+[RedirectTube](https://github.com/MStankiewiczOfficial/RedirectTube), on the other hand, doesn’t automatically open YouTube links in FreeTube. Instead, it adds buttons to the toolbar and context menu, which you can click to open videos in FreeTube manually.
+
+- Download LibRedirect from [Mozilla Add-ons](https://addons.mozilla.org/firefox/addon/libredirect/) (for Firefox based-browsers) or [Chrome Web Store](https://libredirect.github.io/download_chromium.html) (for Chrome and Chromium-based browsers).
+
+- Download from [Mozilla Add-ons](https://addons.mozilla.org/firefox/addon/redirecttube/) (for Firefox based-browsers).
 
 If you have issues with the extension working with FreeTube, please create an issue in the [FreeTube Repository](https://github.com/FreeTubeApp/FreeTube) instead of the extension repository. Most if not all problems is a problem with FreeTube itself and not a problem with the extension.
