I installed click to call on my firefox 11 as an add-on. Now my computer lags or freezes for 5-10 seconds every 5-10 seconds!!! It is sooooo annoying. I cannot play games or type even a basic e-mail. If I keep typing it remembers it, just freezes for awhile first! If I disable it and restart firefox then everything is normal!!! But as I need the click to call daily, this is so frustrating!!! Any ideas PLEASE!!!!
