I have tried all the step by step articles.

Checked Network Proxy, IPv6, dnsPrefetch. Refreshed Firefox. Uninstalled FIrefox/Reinstalled.

When to apple firewall (which is disabled), enabled it and added firefox as an exception.

I'm out of options? Other ideas?

Please consider turning on send info to Mozilla before posting a question. This helps us help you. As I have no info from your system that would help see things that cause issues.

What Firewall are you using ? What Firefox Version please ? What blockers are you using ? Was this working before a Apple Update ? Have you checked the Apple/Mac Forums for issues ?

I do not know where the folders are for a Mac so will provide Windows info and let you figure it out please : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Note: your Firefox Profile is saved. But you should make a back up before you do :

Reinstall with Current Release Firefox 58.0.2 with a Full Version Installer

Please let us know if this solved your issue or if need further assistance
