Thanks for the report, I was able to reproduce the issue.

Note: The issue is not reproducible on Chrome where I'm redirected to Google Play.

Tested with: Browser / Version: Firefox Nightly 210404 (🦎 89.0a1-20210403093157) Operating System: Google Pixel 5 (Android 11) - 1080 x 2340 pixels, 19.5:9 ratio (~432 ppi density)

Moving to Needsdiagnosis for further investigation.

This is based on UA detection.

When I spoof as Chrome and click on the button a GET request is sent to https://approach.yahoo.jp/ host and it returns a 302 redirect to the play store with intent://

I case of Firefox, it just returns a html page in response. The following code is executed to perform redirect:

// fallback to redirect if could not open app or back to from app
            var redirect = function() {
                var loaded = location.hash.substr(1)|0;
                var now = Date.now()/1000|0;
                if (now - loaded > 5) {
                    location.replace(leaveRedirecorUrl);
                    if (timer) { clearInterval(timer); }
                }
            };

            // set hash and execute approach
            if (!location.hash) { location.hash = (Date.now()/1000|0); }
            timer = setInterval(redirect, 1000);

The site should adjust UA detection rule for Firefox, to make it receive intent similar to Chrome. Lets try to contact them
