Take a look at the above New York Times article URL with today's build and with IE. IE displays it correctly, but with Mozilla, the layout is messed up, making it very inconvenient to read. This happens with other New York Times articles also. It used to work fine in Mozilla until recently.
This is a dup of bug 86075, a recent regression. There is already a patch, I hope it will be checked in soon. Thanks for testing Mozilla! *** This bug has been marked as a duplicate of 86075 ***
