Firefox began returning a PR_CONNECT_RESET_ERROR error on all websites a few days ago. Chrome likewise. MIcrosoft Edge is working fine. I am running Windows 7 with Kaspersky. I tried turning off the Windows Firewall and the Kaspersky protection, but it didn't help. I also tried disabling plugins, theme, and add-ons but it still didn't help. Any suggestions?

I just updated my Kaspersky. I forgot to reboot and had similar issues. Can you disable Kaspersky, reboot, and try again. Did you try with Firefox in Safe Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#w_how-to-start-firefox-in-4troubleshoot-modesf5safe-modesf

I disabled all the Kaspersky features and rebooted. It didn't help. Firefox in troubleshooting mode produced the same error. Running Windows 7 in Safe Mode with Networking worked.

Thanks for your help.
