Alternative frontends for web services such as YouTube, Twitter, TikTok and other websites can help you protect your data.
More information
Instead of YouTube, for example, you can use one of the numerous Invidious instances such as yewtu.be in the browser or the apps FreeTubeAndroid, LibreTube, Tubular or NewPipe. This allows you to avoid advertising and protect your privacy at the same time. You can also install LibRedirect for FireFox. This plugin automatically redirects you to an alternative frontend when surfing the internet. Large companies such as YouTube go to great lengths to make alternative frontends unusable or block them again and again. Don't give up if it doesn't work on the first try!
In general, however, it should be emphasized that it is better to avoid such platforms in general and to prefer open source solutions from the Fediverse.
