Cingular Minute Reminder

Going over your allowed minutes isn't fun. Prices start to skyrocket once that last little minute is used up. If you're fortunate (or unfortunate) to have Cingular as your calling plan, there is a ray of hope. Using the Cingular Minute Minder extension for Firefox, you can keep track of how many are remaining. Clicking on the Cingular logo brings up a popup with more detailed information.
