Every time I use Facebook, I get an "unresponsive script" error. Why?

Whenever I'm on Facebook, I get an "unresponsive script" error. A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.

Script: chrome://ciff/content/core/HeaderProcessor.js:20

URL of affected sites

http://

Re: Every time I use Facebook, I get an "unresponsive script" error. Why?

Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. You can use "Disable all add-ons" on the Troubleshoot Firefox issues using Safe Mode start window to disable all extensions. You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

I tried the suggestions above and I still get the error. Any one have any ideas?
