We appreciate your report. I was not able to reproduce the issue:

Tested with:

Browser / Version: Firefox Focus Release 112.1.0 (371041824-🦎112.0.1-20230414125621🦎) 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)

Suggestion: Try clearing cache/data/cookies, disabling add-ons and Ad-blocker (if available) and extensions or use a clean profile, and check again? If there are any changes made to the default settings of the browser (e.g. in about:config) please revert to the default settings and try again. Also, have the required cookies been accepted for this page?

I have to amend that I was using Firefox Klar and not Firefox Focus, I was unaware those were different browsers.

I could trace the issue to the setting: Settings > Privacy & Security > Block other content trackers While it warns that it could cause pages to behave unexpectedly, this is the first site I encountered issues on.

Thank you for your time looking into this

@Pixdigit Thanks for the updated info. I was indeed able to reproduce the issue with the said setting active.

Please refer to: https://bugzilla.mozilla.org/show_bug.cgi?id=1831891 for future updates and workarounds.

Browser / Version: Firefox Focus Release 113.0 (371220128-🦎113.0-20230501151611🦎)/ Firefox Fenix Nightly 114.0a1 (2015949187-🦎114.0a1-20230507095340🦎)/ Firefox Focus Nightly 114.0a1 (371271609-🦎114.0a1-20230507095340🦎) 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)

1. Reproducible regardless of the status of ETP.
