Error message in Firefox, but not Chrome

When I go to the main client area on my site in Firefox, I now get this message:

Warning: Cannot modify header information - headers already sent by (output started at /home/booktour/public_html/_sites/book-tours.com/wp-content/themes/canvas/header.php:11) in /home/booktour/public_html/_sites/book-tours.com/wp-includes/pluggable.php on line 1178

But in Chrome it shows without a problem.

    Hi, Dark Scream!

    This error is almost always the result of extra whitespace before the opening or closing php tags in one of your files, typically your theme's functions.php file, wp-config.php, or in this case, it may be Canvas' header.php. Open these files in a plain text editor after downloading them via FTP, and see if you can spot any extra whitespace in those spots. If so, remove it, resave and reupload the files.

    That should resolve it in any browser. : )

    Thanks, Dark Scream!
