Firefox cannot connect to any website; states "Performing a TLS handshake to ..." and hangs at this point.
Suddenly, Firefox cannot connect to any website. It starts normally, but when a URL is entered, the lower left states "Performing a TLS handshake to www.xxx.xxx" where xxx.xxx is the requested website. I refreshed Firefox, and I also started Firefox with Add-Ons Disabled, but the same problem always occurs. I tried turning off antivirus software, and also tried turning off Windows Firewall. None of these solved the problem. Running Windows 10 and latest Firefox (54.0.1 32-bit). Please help.

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen or hold down the Shift key) to see whether that has effect.
I have this problem with one site only on my Mac. StockCharts.com. No similar problems on any other websites. StockCharts told me no one else had reported this problem. I CAN log onto Stockcharts via Safari. As the original question had it...this only started happening about two versions of Firefox back. Am not a technical person and hope there's a simple (VERY simple) solution. Thank you.
Try to disable IPv6 (check for other possible causes as well).
BINGO! That did it. Thank you very much.
