Firefox ერთობის განხილვა

I have attached a snip of my Firefox GUI.

Glaring white backgrounds in webpage GUIs are, simply, a Pain in the Eyes! I like to get rid of them and I have done for the webpage text background you can see in the image. Now, what I would like to be able to do is to set the same colour as the text background in the URL window and the Bookmarks window.

Is this possible? How is it done?

Thanks

MacOS 26.0.1 Tahoe Firefox 143.0.4 (aarch64)

There is a white border around the webpage content in the browser (screenshot attached). This border exists even in troubleshooting mode, with all extensions disabled, regardless of toolbars or theme, etc. The only place it does not appear is the about: pages (screenshot attached). I've uninstalled and reinstalled Firefox and updated MacOS. The issue disappears when I quit and reopen Firefox but reappears when I resize the window. Is there some obvious checkbox setting I'm missing? I cannot figure out what is causing this. Thanks for any help.
