Firefox's user interface changed again. I like the old, blocky visuals. How do I get them back?

I've already tried about:config>browser.proton.enabled

I don't know what you mean by blocky version. To change the UI you need css: https://support.mozilla.org/en-US/questions/1346582#answer-1434487

After learning the terms for the UI's, I would like to specify that I would like to revert my browser back to the "Photon" appearance.
