Cloudflare infinite loop on Firefox Nightly 134 vs missing bottom shortcut customization in Nightly 155

Hi Firefox Support / Dev Team, I am writing regarding an issue with Firefox Nightly on Android. The Problem: I use Firefox Nightly v134 as my daily browser (134.0a1 - Build #2016052927). I really depend on the bottom navigation bar shortcuts because it has dedicated Back and Forward buttons next to the + button. This allows me to go forward and backward instantly without opening the three-dot menu, which is extremely convenient. Recently, Cloudflare verification (challenges.cloudflare.com on sites like wallhaven.cc) stopped working in version 134. Every time I check the "Verify you are human" box, the page refreshes and asks me to check the box again in an endless loop. Version Comparison: '''Firefox Nightly v134: Has the custom bottom navigation shortcuts (Back & Forward buttons directly accessible), but Cloudflare verification is broken (endless verification loop).''' '''Firefox Nightly v155: (155.0a1 - Build #2016178399) Cloudflare verification works, but the bottom bar layout/shortcuts changed and no longer displays the Forward button shortcut.''' My Request: Is there a fix for the Cloudflare verification challenge on version 134? Or, if v134 is deprecated, could you please add the option to customize/restore the Forward button shortcut on the bottom navigation bar in version 155? Device Info: OS: Android 11 Affected versions: Firefox Nightly 134.0a1 and 155.0a1 Thanks for your help!
