@RL_Dane I don't dislike hamburger menus, both my Thunderbird and Firefox UIs are heavily modified by user stylesheets, but there is one thing that I use somewhat frequently in Firefox that you can't access in any other way but the menus — offline mode. Which is very useful when switching proxies. Because once one of the FF networking thread dies when you shut the proxy down there is no way to bring it back to life, you can only restart Firefox 🤪
