FAQ

  1. What is the Simple Checker for Gmail™ extension?

    Simple Checker for Gmail™ is a very lightweight add-on to get notified when a new email arrives. Unless other similar add-ons, there is no sound notification nor desktop notification. Just the toolbar's badge text is updated once an email is marked as read or unread or a new email is received in your inbox folder. The idea is to have a distraction-free checker for Gmail

  2. What's new in this version?

    Please check the Logs section.

  3. How does Simple Checker for Gmail™ extension work and why there is no need to enter username and password?

    Simple Checker for Gmail™ is run in the context of your browser. It means the extension can access to Gmail whenever you are logged-in. To make sure the extension works fine, you need to always be logged-in. You can hover your mouse over the toolbar button to see if the extension can connect to Gmail or not. Basically, Simple Checker for Gmail™ fetches Gmail feed, https://mail.google.com/mail/u/0/feed/atom, and extracts the number of unread emails from the response.

  4. What is the time interval between unread checks and can I modify it?

    By default Simple Checker for Gmail™ extension fetches Gmail feed every 5 minutes. Note that the extension also listens for some particular URLs to update the unread count if an email is marked as read or unread from Gmail UI. It is recommended to keep the default interval, but if you really want to change the interval follow:

    Chrome/Opera: Open "chrome://extensions/" in a browser tab. Click on "Inspect views: lib/chrome/background.html" just beneath the extension. A new inspect window opens up. Go to Console tab and paste chrome.storage.local.set({"times.period": 10}); change "10" with your preferred time interval.

    Firefox: Open "about:config" in a browser tab. Create a new integer preference by right clicking on the page. Insert extensions.jid1-fmmMm36yhukioOuza@jetpack.times.period as the name of the preference and and the preferred time interval as the value of the preference. If you already have created the preference, search for it and change its value.

    Note that the interval is in minutes and the minimum acceptable interval is 2 minutes.

  5. I have more than one account and would like to set Simple Checker for Gmail™ to check my second account. Is this possible?

    Yes, follow these steps:

    Chrome/Opera: Open "chrome://extensions/" in a browser tab. Click on "Inspect views: lib/chrome/background.html" just beneath the extension. A new inspect window opens up. Go to Console tab and paste chrome.storage.local.set({"gmail.id": 1}) in the console and press return to check the second account instead of the first one.

    Firefox: Open "about:config" in a browser tab. Create a new integer preference with the following info: name: extensions.jid1-fmmMm36yhukioOuza@jetpack.gmail.id and value of 1.

    Note that Simple Checker for Gmail™ add-on cannot check more than one account at a time. You can try Gmail™ Notifier or Gmail™ Notifier Plus if you need more complex checker extensions.

  6. Why the extension requires permission to access "https://mail.google.com/mail/*" and "https://accounts.google.com/*" URLs?

    The first URL is used to fetch Gmail feed. The second one is used to detect login and logout events.

  7. There doesn't seem to be a way to force the extension to fetch new emails from server. Is there any way to trigger new update?

    Simply press the button and let the Gmail page open up. You can close the page after a few seconds as there is a trigger event when Gmail page is opened.
