Thanks for the report @sling-shot , I was able to reproduce the issue.
Not reproducible on Chrome.

Debugger:

Tested with:
Browser / Version: Firefox Nightly 63.0a1 (2018-07-19)
Operating System: Huawei P10 (Android 7.0) - 1080 x 1920 pixels (~432 ppi pixel density), Samsung Galaxy S7 Edge (Android 7.0) - Resolution 1440 x 2560 pixels (~534 ppi pixel density)

Moving to Needsdiagnosis for further investigation.

For the record, I also did a little troubleshooting before the user posted this issue. The page also breaks similarly for GeckoView/Focus. If I do a UA-spoof as Chrome, it doesn't break. As such this is likely a faulty UA-sniff on the page itself (whether it's server-side of client-side remains unknown).

no redirect server side on rbi.org.in
but one on m.rbi.org.in

and it's why we get an infinite redirect issue.

and… ouch…

    //Redirect to mobile site start
    function detectmob() {
      if (screen.width <= 599 || screen.Height <= 975) {
        return true;
      } else {
        return false;
      }
    }

    if (detectmob()) {
      window.location.href = "https://m.rbi.org.in" + window.location.pathname;


    }
    //Redirect to mobile site End

so a mobile device is something that has a screen width smaller than 600px
or a height inferior to 975px

and for the mobile site configuration (server side sniffing), Firefox Android don't exist.
