We appreciate your report. I was able to reproduce the issue using Firefox Focus (Release and Nightly) and on the latest Firefox Fenix Nightly on an Android 11 device:

Tested with:

Browser / Version: Firefox Focus Release 101.1.1 (361470144-🦎101.0-20220526203855)/ Firefox Fenix Nightly 103.0a1 (2015884683-🦎103.0a1-20220605065813🦎)/ Firefox Focus Nightly 103.0a1 (361561708-🦎103.0a1-20220605065813🦎) Operating System: Samsung A51 (Android 11) -1080 × 2400 pixels 20:9 aspect ratio (~405 ppi density) Operating System: Google Pixel 3 (Android 12) -1080 x 2160 pixels, 18:9 ratio (~443 ppi density)

Notes:

1. Reproducible regardless of the status of ETP.
2. Reproducible on the latest build of Firefox Fenix Nightly.
3. Works as expected using Chrome and on Android 12.

Moving this to NeedsDiagnosis for further investigations.

This is based on UA detection, the site is disabling back button action for all mobile browsers other than Chrome:

window.isMobile = (DeviceDetector.parse().type == 'Mobile');
window.isTablet = (DeviceDetector.parse().type == 'Tablet');
window.isChrome = (DeviceDetector.parse().browser == 'Chrome');
window.isDesktop = (!isMobile && !isTablet);
if (!isDesktop && !isChrome) {
  // disable back button
  history.pushState(null, null, location.href);
  history.back();
  history.forward();
  window.onpopstate = function () {
    history.go(1);
  };
}

Let's move to needscontact.
