No change at all. I'm writing in that firefox process now. Having Blogger open in the current tab keeps Xorg CPU usage high as documented, even when I have Firefox minimized.

The xwiki.org page does cause Xorg CPU usage to go as high as Blogger during loading stage or when changing window size, but it is tame when kept minimized and/or its size unchanged.

I suspect some JavaScript code might cause this, but that's my uninformed opinion (after all, it's Xorg using CPU) and to be taken with a (few) grain(s) of salt.
