Why do I have a white screen instead of a blue one?

i think earlier you mentioned you were using firefox?

I'm on a mac, but these steps should be the same/similar on windows.

Go into the settings/preferences screen and click on the "content" icon.

There should be a section called "Fonts & Colors", with a "Colors" button. Click that button

In the window that appears, make sure that the option "Allow pages to choose their own colors, instead of my selections above" is checked.

If this is NOT checked, you'll simply get a white background, so I suspect this is the cause for what you're seeing.

So make sure that option is checked and let us know if it fixes it.
