MailCheck lets you browse Firefox and see incoming mails

Many of us are used to logging into our email inbox every day, but is there a faster and better way? With this new feature from GMX, emails can be seen directly in the toolbar window while you’re browsing Firefox. Since many emails need replying to as quickly as possible, MailCheck and Firefox have created the best solution for those who need convenience.


Keep in the loop with MailCheck for Firefox

One of the most useful add-ons you’ll need for emailing, MailCheck gives you direct access to your GMX email account from your Firefox browser. After installing the free add-on, you’ll see an envelope icon displayed in the Firefox toolbar. With this, you'll get an up-to-date status on your email account. If you use the GMX add-on for Firefox, email notifications will pop up in your browser window as soon as the mail arrives at your inbox. This instant access to your GMX account saves you so much time since you don’t have to constantly sign in to see if any new emails have appeared. MailCheck keeps you in the know and is only a click away when using Firefox.

Signing in made so much easier with the one-click login feature

The MailCheck for Firefox add-on is all about saving you precious time, so you'll be glad to know that you only have to log into your GMX account once. Fast and easy to follow, it's just a matter of clicking on the envelope icon in the Firefox browser whenever you need to see your emails. Just like creating an email address, these things should be quick! Skip the long and boring process of using search engines to find the right log-in page or having to re-enter your details in different browser tabs. MailCheck makes it easy with Firefox, using the one-click login system.

Customize the add-on to your liking

When you have MailCheck for Firefox, you can either keep the recommended default settings for the GMX feature, or you can customize it to your liking. You can not only enable or disable incoming pop-up messages that notify you of new emails, but also sound notifications. Another great thing about MailCheck is that you can add multiple email addresses. This means that if you have personal and business GMX accounts, you can see emails and notifications for both addresses at once, directly in Firefox. Email accounts can also be added and removed as you like, which means you have total control over how you view your account. Personalize your mail experience the way you want it!
