Firefox freeze/hang while browsing facebook

Ever since I upgraded my firefox to version 3.5.3, everytime I went into facebook, my browser would freeze or worse hang (not responding) some time. Note that I never face any issue with the previous version of firefox. Anyone out there face the same issue too? Well I have a solution for you, just follow the steps below:
Open your firefox go to Tools, then locate Add-ons
You should then see a new window opened. Look for Yontoo Layers and click on the Disable button

Once you have done, click restart firefox


There done in 3 simple steps, and now you can browse facebook in your all time favorite firefox browser without getting freezed/hanged.

Enjoy
