Make sure you are not blocking content.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

One issue that seems more common lately is Firefox's Tracking Protection feature. When it is blocking content in a page, a shield icon will appear at the left end of the address bar next to the padlock icon. This article has more info on managing this feature: Tracking Protection {web link}

I don't see how this relates. I am trying to login to support from the Google Chrome browser.

Hello ,

you can,but

would be better if you use firefox:

How do I sign up for a Firefox Account?

You can access the sign up page on each Mozilla service, or visit the Firefox Accounts signup page and follow the steps below:

1. Enter your email address, password and age, then click Create account.
2. When the confirmation email arrives, click on the verification link.
3. Once your account has been verified, sign in to your favorite Mozilla Service using your newly created account. After you sign up, you can also sign in and add an image to your profile.

If you have problems verifying your account, please see :[https://support.mozilla.org/en-US/kb/im-having-problems-confirming-my-fir...]
