I have written an extension for Firefox that monitors your Sprint wireless usage, and reports it in the browser status bar. It can be downloaded from http://sprint-minutes-ticker.blogspot.com.
Cool, will be waiting for it. I assume I can update the extension direct from FireFox and not go to site to redownload? Also, you need a more obvious spot on your site to download. Was hard to find the download link.
Thanks for the feedback. I agree that the web page could be easier to use. I'll spend some time improving it. Unfortunately, the first release was latest-version unaware, so you'll have to do a manual download. I'll be sure to announce the new one here.
We appreciate the effort you've put into this. Still no-go for family plan accounts. Just says 'checking usage'. Hoping for a fix. Really could use a tracker like this.
