Something changed with one of the Fire Fox updates. I can no longer log into my Spotify account on my home computer. For some reason the login page shows me a log in error. Nothing has changed on my Spotify account settings. The current log in works in Google Chrome and in the the Soptify app. I can use the same log in on my work computer using Fire Fox as well. I don't know what changed with Fire Fox on my home computer and I don't know where to look to resolve the problem. Can you help?

thank you, Scott,
