@Evkob @Gargari, this is not so clear, Mozilla has made a pact with the devil some years ago and is sponsored by Google, it even employs several Google devs who develop FF, the risk of depending on outside investors. Chromium is certainly from Google, but it is, just like Gecko, FOSS and therefore every browser developer is free to gut it, throwing out any Google API, which they are doing in Vivaldi (leaving some to the user’s choice in settings), no homecalls to Google.
