Luckily this can be reverted via the secret settings https://firefox-source-docs.mozilla.org/mobile/android/fenix/Secret-settings-debug-menu-instructions.html

I just got this new menu as well, and instantly hate it. It takes up WAY more space without actually providing any new functionality In fact, it has taken away functionality!!

It has also put buttons I use very regularly even further away, under even more submenus. I genuinely do not see the point of this new menu...

When I saw it, I immediately looked in the secret settings to see if it could be reverted, but no such luck:

The new menu doesn't contain at least two very requently used actions: - reload the page - go forward There is no way to disable the new menu and revert the old behavior.

I have Reload on the top bar (lock, URL, Share, Reload) and Forward on the bottom bar (Back, Forward, New Tab, Tabs, Menu). I'm not in love with two-bar layout.
