Writer default document background colour and custom about:b

Writer default document background colour and custom about:b

I use a custom about:blank page on Firefox (with the FF logo on it). All my documents look 'transparent', I can see the logo through the text.

I guess that using about:blank was simpler than changing the background colour to white - which would work in 90-odd percent of cases, but doesn't with me.

Thought you ought to know.

Cheers.
