I found another really neat firefox extension. Its called minutes used and it tracks the number of minutes you have used and then gives you detail on whether the minutes are in-network, peak, off peak, etc. It even gives you the ability the make the number red when it goes over a certain threshold.This is really neat and well done extension to make sure you don’t go over your minutes. I got the one for verizon since my phone is verizon. It looks like there is an extension for TMobile too though. Go see for yourself here.
