Perfect mail notification extension, does exactly what is promised certainly when you contribute an amount you will have this fixed on most browsers.

I've been using this extension for years, always been happy with is.

One feature request: I would like to have the ability to have an email account added, but for it not to include emails from that account added in the little red number. (I have my wife's email accounts added on the desktop, but I don't need a running tally of how many emails she has unread, and I don't want to be bothering her and telling her to clean out her email accounts.)

I have been using this add-on for close to one year now and it has been a lifesaver when I am waiting for a reply knowing when it arrives. EXCELLENT! Highly recommended.

I just realized I've been using this addon since 2011? 2012? It's been a massive amount of time, and it's still one of the first I install when setting up a new browser.

I can't recall ever having an issue, it's rock solid and works perfectly for how I use email.

I monitor 9 diff. email addresses from Checker Plus. Nothing better.
