I've had an issue lately where some web pages were not looking or operating right in Firefox on my home machine but were fine in Firefox at work. I have them set up essentially the same so I couldn't figure out what it could be. Today at work I remember a fix I read about a while back and gave it a try tonight it things seem to be working great again.

The fix:
Shutdown Firefox, go to your Firefox profile directory and delete the file named XUL.mfl. That file is a cache for javascript and other user interface elements. Sometimes it gets corrupt for what ever reason. Since it's a cache you can safely delete it and it will rebuild the next time you launch Firefox.

I've gone a step further and edited my FixFox.bat batch file so that xul.mfl gets deleted when I run it.
