Rated 5 out of 5 stars

Fabulous. I have changed it to check my emails every 1min and it checks 3 of my accounts (gmail, hotmail and yahoo) simultaneously.
I love the fact that the developer constantly updates this extension to keep us users happy.

Very Handy Add-on Rated 5 out of 5 stars

Been using this add-on for a very long time and it has never failed me. Allows multiple accounts to be added from different email accounts eg gmail, hotmail, yahoo and gives you the number of unread emails next to your browser address bar. When clicking on the letter, it automatically opens your email account, no need for signing in.

Thanks dev, made my life a whole lot easier.

Very Very Useful Rated 5 out of 5 stars

Checks your emails for you, and when there is an email, it notifies you. You can add multiple email accounts, like me, I have added gmail, hotmail and yahoo. It also gives the option to change the default check interval. I changed mine to 1min so every 1min it checks my inbox for my 3 email accounts.
Thanks developer, you have really saved me a lot of time.
