This has been happening both at work on my PC and at home on my iMac. Pandora locks up. Videos lock up. Facebook won't load on my iMac under firefox. And it is not solved by restarting the program or the computer. I make sure to install all updates when requested. I am forced to use Chrome now! Oh the horror!

Please give some details; what computers systems, what Firefox version?

Does this happen on some web sites , many?

Start Firefox in Safe Mode {web link} While you are in safe mode;

Type about:preferences#advanced<Enter> in the address bar.

Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.

Poke around safe web sites. Are there any problems?

Then restart.
