Refused connection to sites worsening

More and more sites can no longer be accessed by Firefox. I work for Lowe's and it started with store site. Then other sites no longer could be reached. Now I cannot login in to my employee account. Always some message regarding incorrect protocol or certificate or some other security issue. None of these sites are bogus. I have tried all the suggestions given in support but it just keeps getting worse. I have used Firefox for years but will be forced to abandon it if I cannot find a solution soon. If you can help, please do.

Are you using a proxy or VPN?

You can check the connection settings.

  • Settings -> General -> Network: Connection -> Settings

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":


It is possible that your firewall or other security software blocks or restricts Firefox without informing you, possibly after detecting changes (update) to the Firefox application. Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access for Firefox and the plugin-container process and the updater process.

See:

Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.
