@tapaniraja Might be it's faster just because of AMP pages served instead of regular pages. That's one of the Google's tricks. Special page format + their CDN to deliver...
@tapaniraja Yeah, I use FF on desktop, Focus on Android. Have Chrome on mobile, but don't use it at all. On desktop, use it only for testing or when a site seems to block on FF.
@tapaniraja I don't browse the web a lot on mobile, as it's very expensive where I live (Benin, West Africa). But remember that calling for same URLs gave them pretty quickly indeed.
