A manifest v3 web extension with minimal permissions that automatically redirects popular sites to privacy friendly frontends - GitHub - libreom/predirect: A manifest v3 web extension with minimal ...
It supports both links and embeds and is available on firefox for android. List of sites is on github. I'm the main developer so you can ask questions.
Libredirect is a manifest v2 extension (can't be published on chrome store) and has permissions for all_urls, predirect is a manifest v3 extension and only has permissions for necessary domains
The sites to be redirected shouldn't be already pre-selected by the extension. E.g I am logged in to Twitter on my browser and installing this extension will unintentionally redirect me to some instance.
And also, maybe the sites for redirection should be added by the user instead of the extension making assumptions. With libredirect I can click more options and add the site to Chrome's handler.
It has a reasonable default of reliable privacy frontends but I may add an onboarding step(already in firefox due to more restrictions in their manifest v3 than chrome) for selecting sites
