webmail notifier gives me popup with all of my email addresses I have declclared but two are displayed in red with the words 'not checked' at the end and they arerealy not checked. Ihave to check them manualy WHY?

I have setup webmail notifier with 5 email addresses out of all of my email addresses. One address is a hotmail address, one is a yahoo address and three are gmail addresses. I mouse over the webmail icon indicator a popup is displayed with the the header '''Webmail Notifier''' bold text then the three gmail addresses on the next three lines . One is displayed in black as the first line. The other two addresses are displayed in the color red on the next two lines with the words 'not checked' at the end of the address. Also the hotmail and yahoo addresses are not displayed in that popup. Why? This plugin is one of the top plugins for me. I tried to make a contribution of $20 through PayPal but PayPal is in the change mode and not working. I have contributed several time for the plugin. Thank you I only use Firefox russellthollen@gmail.com
