While looking for the source i found this:
Firefox Tests Privacy-Friendly Web Page Translations

It’s coming bby!

I’ve been running Firefox as my default browser on my phone since 2018 without webkit. Even other apps opens their links with geckoview. It started with FF Focus, shortly after FF Preview, then FF beta and since last year FF for Android.

Apple on the other hand…

Sources:

• Firefox Focus gets GeckoView
• Firefox Preview gets GeckoView
• Archived github repo for preview, beta, and main android
