Verizon Usage Monitor for Mozilla Firefox

Tired of paying ridiculous overage fees for minutes or data used with your Verizon cellular plan?  Verizon Usage Monitor is for you!

Verizon Usage Monitor is an extension for Mozilla Firefox that will help prevent you from going over your wireless plan's monthly allotment of minutes or data by enabling you to easily monitor your minutes and data usage for your Verizon account.  Simply being aware of your current usage can help you carefully consider future usage, encourage someone on your account to minimize their usage until the next billing cycle, or call Verizon to increase your minute allowance.  more...
