(the live CD on the website)

The contents of Firefox's URL bar, instead of showing the text of the URL,
shows a black and/or gray bar where the text should be.  The text is still
there -- it can be selected and copied -- it just can't be seen.  This
happens both when running from the live CD, and after installation.
Everything else (having to do with the display, and otherwise) works fine
and is perfectly normal.  The problem doesn't occur when running from the
Xubuntu 14.04 live CD.  Is there a way to fix it?

Thanks.
