Thank you for your reply. Your suggested solutions are not complete, however.

The status bar is not persistent.

Also, for whatever reason, the URLs displayed in the status bar are cut off with an ellipsis, even when they would fit inside the window.

The menu bar -- File, Edit, View, etc. -- is still not displayed. And when it is displayed, the keyboard accelerators are not. I do realize this is in part the window manager and OS's accomplishments.

By the way, most of the actions you described are not even possible without using the mouse. Firefox, and most desktop applications, used to be 100% accessible without using the mouse. (Mac has always been an exception, but it was covered 100% on Windows and close to complete on GNU.)
