Firefox can't connect to web-sites with disabled firewall
Latest firefox works badly with Avira Antivirus component web-protection. It seldoms stops viewing all web-sites while all other brorsers works just fine.
Hi Sirahei, Thank you for your question, I understand that Avira Antivirus component web-protection when enabled and disabled that websites do not load in Firefox.
Please update to the most recent version of Firefox 37.0.1 to make sure it was not the ssl fallback change:
Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.
