The CSS animation at the bottom of each page,
consisting of something resembling four squares,
is highly annoying.

It is located right before the "footer"
and I believe it is included under the title
"standalone-loader-cube-wrapper".

It is not straightforward to prevent a browser
from displaying it. Although using firefox
this might be achieved by adding the following
line to userContent.css:

div.standalone-loader-cube-wrapper{display: none; visibility: hidden;}

However I would not know how to eliminate it
using other browsers. It would be simpler that
you consider eliminating at the source.

I have little doubt that many users, like myself,
shall be grateful if you eliminate this annoyance.

Thanks.
