Firefox 15 & 16 crashes when looking at Google Books while Norton Toolbar enabled

Hi,

I am able to repeatedly generate a Firefox crash related to Norton Toolbar 2012.5.7.2 when viewing Google's scanned books, particularly when clicking on the "About this book" links. An example is here:

 

http://books.google.com/books/about/Beitr%C3%A4ge_zur_M%C3%BCnzgeschichte_des_Elsa%C3%9F.html?id=F2SxtwAACAAJ

 

When the Toolbar addon is enabled, the page crashes Firefox 15 and 16 on my machine. Disabling the Toolbar addon ends the issue. Can anyone else verify this or has it been reported? Thanks!
