I got a chance to look in on the about:config, and I list the available layout css controls. It took me a one-at-a-time copy-paste to a text editor, then a copy-paste of that content in here.

The format is different from what I was looking at in the editing screen, but everything I saw there is listed, along with its settings. It does not contain the setting I was requested to change.

layout.css.all-shorthand.enabled;true layout.css.background-blend-mode.enabled;false layout.css.devPixelsPerPx;-1.0 layout.css.dpi;-1 layout.css.filters.enabled;false layout.css.font-features.enabled;false layout.css.image-orientation.enabled;true layout.css.masking.enabled;false layout.css.mix-blend-mode.enabled;false layout.css.osx-font-smoothing.enabled;false layout.css.prefixes.animations;true layout.css.prefixes.border-image;true layout.css.prefixes.transforms;true

I still have the issue in Windows XP of conflict between the browser using the bottom corner and the web site wanting to use the bottom corner. I see the time.com scroll-down button at the bottom of the page and I get the resize control cursor instead when I try to use this scroll control.

Particularly aggravating when I am in my Gmail account, for there too, the bottom of the screen is claimed by the web site and overruled by the window resize control.

It's my understanding from the Gmail user who posted me screen shots of his Firefox "sharing the road" shall we say. I am using the Windows XP theme, and that changed nothing.
