can't "Create a New Contact" in Firefox anymore
I used to use Firefox (91.0.2, last update) to do all my Xfinity Voice stuff. But lately, when I do Options-Add Contact-Create New Contact, and enter the new contact info, and press Save, nothing happens. In fact, many of my contacts are messed up.
But Chrome (92.0) works just fine.
What's going on???? I have tried clearing my cache, etc, and that doesn't help. Has Xfinity abandoned Firefox?
