How do I get rid of the empty space at the top of my screen caused by your update putting "Tab" up there which I had gotten rid of years ago & survived updates
The new update has messed up my screen. There is now about 20 sq. inches of empty space to the right of the menu bar, which used to be on the same line as the URL space & a "Tab" space that I don't need because I never use tabs.

Tabs is another issue. As for space please go to the 3 Bar Menu and then Click Customize. You can move things around here as well as add/remove or reorder them.
Here's a more comprehensive project which affects not only tabs but brings back the old "grid-style" options menu. https://github.com/axydavid/FirefoxUI/blob/master/README.md
It isn't completely possible to use the Australis design with Firefox 57, but depending on what you want, you might be able to customize the UI to look more like the old one: This project: https://github.com/wilfredwee/photon-australis lets you have the old tab bar appearance back in Firefox 57. You can remove the space around the address bar by right-clicking on the spaces, and choosing "remove from toolbar".
Note the Black Theme is just a Example and can be found in Customize.
