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.
So basically tighter permissions and using newer APIs. As for the Chrome stuff, as a Firefox user posting in a Firefox community, it's of little consequence to me. But I look forward to trying out this extension.
Edit: Tried it and it kinda falls over at the first hurdle. I installed it and then tried to follow links to Tiktok and Instagram only to end up on the official sites.
Also the UI is kinda unstyled. It feels like when you first learn Java.
There is an onboarding step for permissions in firefox version(due to more restrictions in manifest v3 than even chrome),so you need to grant permissions, unstyled UI is intended but I will add style with a minimal ui css framework in near future
Firefox is stricter than chrome in manifest v3 that it provides no way to request host permissions at install time, there is a onboarding page after installation of addon where you can grant permissions to hosts
