The headings and subheadings on some (but not all) sites bleed together into one line of text or the text appears but all or partially outside of the box in which it is intended to reside. I have this problem with MSNBC, for example. The headings at the top of the webpage (TODAY, for example) combine with the next line of subheadings (World, for example) after appearing separately for 1 or 2 seconds. At the same moment, a message appears saying that Firefox has prevented the page from automatically reloading. When I respond to that message by clicking the Allow button next to the message, Firefox appears to reboot the web page and the same message of preventing automatic reloading reappears. I experience the same problem with the New York Daily News website and some others but with other websites such as the BBC I experience no problem.
