sucks will work couple days then stop operating where cant log in and must go throught google search yahoo mail just to get into my email

Does not work, I am already logged in and does not log in on the add on. I tried to log into the add on, it directs me to yahoo mail which I am already logged in. The Add on is still not logged into my email.

Lost my Firefox, can't get rid of app mailside. bar

I cannot access a user-defined folder I made, I get "No Internet Connection" message —works fine for Inbox though. On the Yahoo Mail site it loads fine, just not on this add-on —if there's a fix, please let me know (like enable Mixed Content or wutev.) This add-on certainly has potential. —Post-Scriptum: No wait ! It works after I restarted FF, I can now open my secret stash folder !

ottimo

It's not a sidebar, at least on my Inspiron. It's a window that shows part of my Yahoo Mail in any web browser. I know it's not supposed to look like this! Can I get any kind of support to have someone look into this?
