Why I'm unable to login to trailhead from Firefox browser?
Since last week, when I try to login Trailhead, I see the below message and it never goes beyond this on Firefox browser:

It opens on Google Chrome, but what's wrong with the Firefox?
Please help.

Please help.
Just try to clear cookies in your browser,
Press Ctrl + Shift + Del in your browser and choose "Everything" as well select all checkbox, then clear.
After that, try to login again. Hope it will work.
Unfortunately, clearing cookies did not help. Trailhead works on Chrome but not on Firefox.
I guess Trailhead is not as cross browser compliant as we would like.
