I have some spreadsheets pulled in from Google docs and it looks like there are display problems when using the dark browser theme (Firefox). It seems that cells without a background color are shaded dark because of the theme, but the text remains black giving a black on black effect.

Compare the light theme on the right with the dark theme on the left:

Is this a bug?

I like the dark theme for the reduced eye strain, so this there a workaround that allows me to keep the dark theme?

Thank you
