I have this problem as well. Unless you go into some sort of shock, the easiest thing to do is just use MS-Explorer if you are running on a Microsoft platform. If you are running on something else try another browser compatible with your platform and/or of course as was said above go back to an older Firefox iteration. This is one reason that I have never quite understood as new versions come out why so many feel compelled to always "update" to the latest edition? A good friend of mine that runs an Internet connectivity site, www.cyberhouse.com, taught me a long time ago not to change unless the new version does something better or new that you really do need. That has kept me out of loads of wasted frustrating time sorting through needless issues.

Mozilla are aware of the issue in Firefox 3.6.14 and are working on a fix, no timescale but they are planning on a quick release. Firefox 3.6.15 will fix the issue with some Java applets not working, which has caused many Pogo games to stop functioning. Mozilla are currently in the process of creating the new version which will then be tested to confirm the fix is working.
