I use a VPN for work, but starting today (6/14/17) Firefox stops connecting to the internet after connecting to the VPN.

No other web browsers have this issue

I have uninstalled and reinstalled Firefox

I have checked the proxy settings and tried all options besides manual setup (I have never had to set up a proxy before)

Issue is the Server Not Found page

Disconnecting the VPN restores functionality
